Because POP3 is not secure PERIOD.
TLS is another protocol to go THROUGH to secure the entire transaction.
You said username and password are sent in clear text then showed code to call a POP3 connection. In the clear is the only way for POP3. If security is added it must be transparent to the client and server.
Select a secured server for your e-mail and non-secure clients simply will not connect.
IMO this should have been left in the grave.

What makes you believe POP3 isn't secure if it uses TLS?
I am questioning the security of the connection in this thread, not POP3.
There are other email checkers on this site using non-secure connections.
Hoping everyone knows they are transmitting there user name and password in clear text.Leave a comment:

??? 10 years and just noticing that a non-secure protocol does not encrypt user name and password???
Use a newer protocol.

Username/password in clear text?

I don't expect anyone else is usinig this email checker (I've found it indispensible for pre checking for unwanted emails - not necessarily spam) but if he is I made some changes. It was brutally slow with large attachments. And I didn't realize why /(Well, I knew but didn't realize.)
Anyway reading another thread mentioning concatenation the other day, it just struck me today that was the reason the program was slow. Far slower than Eudora is when retrieving the email, for example
By pre-allocating the message to be retrieved size, it now checks the mail as fast, maybe even faster, than Eudora.
Here's the code JIC anyone is interested: (.exe is at link below)

Dunno if any are interested but I replaced the code above with exciting mind blowing astonishing new features. {geez, I can make myself laugh pretty easily}.
When the program starts up, if no .ini is present, it automatically (requiring no effort from the user) pops up a handsome Ini Dialog where Server, User name, etc. can be entered. Or the user can access the Ini Dialog at start up via a special key...
It has been exhaustively tested (I ran it at least twice) before being posted here so ...
(Website .exe updated too. Link posted previously)

I am SO esscited! Tonight I added a Graphic Inkey to Mike Doty's nifty Sleeper routine (http://www.powerbasic.com/support/pb...ad.php?t=40472) that overlays the Title in the Loud MessageBox. (No Dialog Set Text for graphic windows - or at least I didn't see it.) AND it's the first time ever using Threads for me (have never seen/had a need). Just too much joy for this old heart all in one night. Am goin' to bed.
Pretty cool I think {grin}.

Thanks John. Works a treat now. Here's what I'm doing. (Note "ptf" prints to a tracking file which makes the whole world go around easier.)

Here is the bulk of the code of a DLL I use. I have just removed the sections that relate to the clients app, it will give you the order of actions.
If you only want to determine if it as email you want to keep then usually replacing the "RETR" command with the "TOP" command so just getting the headers is enough and then only "DELE" the ones you don't want. If you use Outlook then to see more details of typical headers the after opening the email go "View", "Options" and it will show you the headers of the email.Code:#COMPILE DLL #DIM ALL GLOBAL MDet() AS MailDetails GLOBAL LstErr AS STRING '------------------------------------------------------------------------------ ' Connect to POP3 mail server.

If you want to display the email, as long as you only display in plain text it is not difficult as even if the sender sent HTML or RTF then it will be repeated in plain text. Nor is it difficult to recover attachments.

Thanks the reply, John. Essentially what I have to do then is:
Aside from coding technique, those are the steps I have to take, right? Or not? Have zero experience with TCPing. I dont mind chasing my tail just so long as it's in the "right" direction. {obscure pun}Code:'pseudo 'Establish connection to server ' STAT to get NumMsgs Then For ctr = 1 To NumMsgs Tcp Print hTcp, "RETR " & Format$(ctr) 'Grab msg Num_Bytes_to_Get = 1024 'to start - most to get at one time 'Now Keep adding 1024 until we have the whole msg ' (maybe use Octets to determine msg len and/or num bytes to get) Reset Msg$ 'Bytes_Needed = Octets_Received 'ie from "+OK 1533 octets" Bytes_Needed = Val("&O1533") Msg_Not_Done: Tcp Recv hTcp, Num_Bytes_to_Get, sTmp Msg$ = msg$ & stmp If Len(msg$) = Bytes_Needed Then 'or instr check for "+OK" or something 'do filter magic here Iterate For 'work on next msg Else Num_Bytes_to_Get = Bytes_Needed - Len(Msg$) If Num_Bytes_to_Get > 1024 Then Num_Bytes_to_Get = 1024 'most to get at one time End If GoTo Msg_Not_Done End If Next ctr Tcp Print hTcp, "Quit" Close Tcp

BASIC compilers and interpreters have always supported a free interspersing of variables, literals and expressions in both intrinsic functions and external calls.Now experienced real men will read that with no trouble, and automatically understand (assume) as sensible. However simple minds won't when they see a " " (literally quoted string) being accepted in a place where the docs call for a long pointer (LPCTSTR lpText,) but an assigned string is not accepted. This simple mind, at least, finds that confusing.
Versus, say, COBOL, where you could never reference a table ("array") element with an expression like..
Instead, the programmer must reduce the expression "A+2" to elementary statements...Code:MOVE Z(A +2) TO X ' BASIC = X = Z(A+2)
(Don't even get into string handling. BASIC is far superior to COBOL when it comes to strings)Code:ADD 2 TO A <<< numeric literal here OK MOVE Z(A) TO X <<< expression here not OK
The PB compilers see "AS ASCIIZ" or "AS LONG" in the DECLARE statement for an external call, and just convert the literal or expression to that data type for you.
Then again, when you start using the WinAPI functions in lieu of the provided intrinsics, you are pretty much on your own as far as the compilers are concerned... the compilers' only responsbilities in this case are to ensure the DECLARE and CALL (express or implied) intrinsics "work as advertised." The conversion of literals and expressions in these cases is pretty much a freebee.

Yes there are depending on what level of checking you are doing to determine if the email is wanted. When the server returns the number of emails it has then each of those emails can be addressed by their individual count number.
So if the server says you have 5 emails the you can send a TOP command for each of those numbers ie
TCP PRINT nTCP, "TOP" + STR$(MsgNumber)
This will return all the header up to and including the blank line seperating the body and the number of lines in the body (whilst this is an optionally accepted command by POP3 servers in modern practice all accept it).
You can then do the bulk of normal spam processing such as comparing to black and white list lookups, subject comparison, reverse address lookups etc.
If your program decides not to accept the email the it deletes it by its number ie
TCP PRINT hTCP,"DELE" + STR$(MsgNumber)
of course if you later try to download the email number you will get an ERR response.

Not really gotten to the gui yet, Mel, though I am using PBWin. Results, so farOriginally posted by Mel Bishop View PostNot a problem, Gosta. Looking forward to seeing your results.
Idle curosity: Have you replaced my "notify" routine?
Am stuck on retrieving the email. I can get the whole pile from the server okay but it *seems* I'd have to parse out each individual email. Is that right? (using the 'Octets' returned)
I mean I can do it okay but it seems there should be an easier method. Just thought I would ask before delving into it.
What I was hoping to be able to use a simple loop, ie
Here's where I am actually at:Code:'psuedo for ctr = 1 to Num_Msgs Get ctr from server Check if good email If not Good then tell server to delete ctr Next ctr
I have searched the forums for examples (using "email retrieval", and other terms) but not having much luck. No doubt lots of examples but get too much 'flotsam' to look through and soon either get sidetracked or frustrated/aggravated. If someone could point to one I'd be grateful.Code:'Note ptf prints to a tracking file Sub Retrieve_Messages(Num_Msgs As Long, Msg_Pile As Long) Local Msg_length, ctr As Long Local msg, buffer, stmp As String Local hTcp As Long hTCP = Pop3Connect(sPop3Host, sUser, sPassword) 'open it up ' Retrieve the page... ptf "Starting" Do Incr ctr '>>>>>>>>no good If ctr > Num_Msgs Then Exit Loop 'got 'em all?

What the procedure wants (according to WinApi Help) isOriginally posted by Michael Mattias View Post

However simple minds won't when they see a " " (literally quoted string) being accepted in a place where the docs call for a long pointer (LPCTSTR lpText,) but an assigned string is not accepted. This simple mind, at least, finds that confusing.The MessageBox function creates, displays, and operates a message box. The message box contains an application-defined message and title, plus any combination of predefined icons and push buttons.
int MessageBox(
HWND hWnd, // handle of owner window

LPCTSTR lpCaption, // address of title of message box
UINT uType // style of message box
);
Parameters
hWnd
Identifies the owner window of the message box to be created. If this parameter is NULL, the message box has no owner window.
lpText
Points to a null-terminated string containing the message to be displayed.
lpCaption
Points to a null-terminated string used for the dialog box title. If this parameter is NULL, the default title Error is used.
uType
Specifies a set of bit flags that determine the contents and behavior of the dialog box. This parameter can be a combination of flags from the following groups of flags.
Specify one of the following flags to indicate the buttons contained in the message box:

I was more concerned with the passing of string literals than variables, but for variables you are right that BYCOPY is expained in the help file... but that help does not talk at all about passing literals as parameters.
It's not flaw, but it's not conditioned. If the procedure being called wants an ASCIIZ parameter in that position - as in this particular example - the STRPTR analogy is correct... since ASCIIZ strings as passed as the address of the data.Just as I now interpret "ByCopy S$" to be the equivalent of a StrPtr variable. (And, of couirse, I now expect you to point out the fatal flaw in that logic.)
However, if the called procedure wants a STRING parameter in that position, what will be passed is the VARPTR of a temporary string - a copy of the original if it's "BYCOPY stringvar," or a freshly-created temporary string if it's " quoted_literal"
Same way the compiler handles numeric literals or expressions: If you call a procedure which expects a numeric parameter...
... you can call it with a numeric literal....Code:FUNCTION FOo (X AS LONG|SINGLE|DOUBLE|EXT|CUR|QUAD) ...
.. and the compiler will handle setting up the value "two" in whatever format required for the procedure Foo's parameter.Code:Z = Foo(2)

Is my help file unique?
Err... yes it is. In the help for "CALL statement" (as I mentioned earlier in the thread).Using BYCOPY (or parens) at the point of call is almost like using a literal in that the compiler will convert the value of that variable to the proper datatype for the called procedure.
MCM
PS: no, that is NOT in the help file, either Windows or PB
I really do recommend reading the topic. The quote is from the PBWin 9 help file. I haven't checked previous versions. It can also be viewed online here.BYCOPY
...
In both cases, a copy of the data is stored in a temporary memory location, and the parameter consists of a 4-byte address of this temporary location. Another way to force BYCOPY is to enclose a variable name in parentheses, so it will appear to the compiler as an expression, rather than just a single variable.

Pete.Leave a comment:
