But, , if I were going to have a GoDo list:

1. Binary attachments
2. Multiple To: address
3. BC/CC
4. Support for HTML and plain text bodies
5. Consistency/broader support for various formats ... "John <[email protected]>", etc.

I know that some of these are already supported by the original author's code. I just didn't have my scope for gbSendMail set that wide.

So if you want to add one of those features, you can check the original author's code to see if it's already available.

Gary,
1) Binary attachments are fairly straightforward, they're usually just base64 encoded -- one of the very first PB SMTP demos (i think in \pb\samples\) shows how to do this

2) Multiple to: address
This is also related to 3) (BCC/CC)
Basically, to send to multiple addresses you simply send "RCPT TO <nextemailaddress>" over and over for each address - you should receive a 250 "success" error code for each valid email address. The resulting email by default is a BCC. If you want to make it a CC (so that ppl can see who else you've sent it to), you simply include the CC field in the email header (alongside the To, From, Subject, Date, X-Mailer etc etc header fields).

4) Support for HTML is kinda easy enough...
Here is a "PLAINTEXT HTML-based" email, that simply says "Hello world"... (note - plaintext, but still with a specified formatting ... with plaintext though you dont actually need to specify these fields like 'Content-Type')

Code:

Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original
Content-Transfer-Encoding: 7bit
 
Hello world

HTML formatted (you'll notice it first has the "plaintext" version, then the HTML version):

Code:

Content-Type: multipart/alternative;
	boundary="----=_NextPart_000_04D8_01CFB33A.E2EC5D50"

This is a multi-part message in MIME format.

------=_NextPart_000_04D8_01CFB33A.E2EC5D50
Content-Type: text/plain;
	charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

Hello world
------=_NextPart_000_04D8_01CFB33A.E2EC5D50
Content-Type: text/html;
	charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=3DContent-Type content=3D"text/html; =
charset=3Diso-8859-1">
<META content=3D"MSHTML 6.00.2900.5512" name=3DGENERATOR>
<STYLE></STYLE>
</HEAD>
<BODY bgColor=3D#ffffff>
<DIV><FONT face=3DArial size=3D2>Hello world</FONT></DIV></BODY></HTML>
------=_NextPart_000_04D8_01CFB33A.E2EC5D50--

Some of these are pretty "raw/native" features though so while they're fairly straight-forward with pure TCP I'm not sure how to accomplish these differences if using say, CDO for example, unless it has some option to support these, although Jose posted a list of about 30 or so options/parameters for that so who knows! HTML email is so common though so im sure there'd be some way, and I know just the man who'd know

Instead of pMessage.TextBody, use pMessage.HtmlBody.

To note... Many servers throttle traffic to save cost (they may say to increase security). Personally, I send messages in batches of no more than 5 ("to" addresses and/or separate messages) without disconnecting, waiting a second or two, then reconnecting and continuing. This seems to keep the sending server from getting "annoyed". Many servers allow 10 with no issues, but in the "wild", I never know what servers my customers will use, so I use 5 to be safer.

Hi Gary,

Am I wrong or the email "From" and "To" are swapped?

Regards,

**Gary Beene** · 8 Aug 2014, 06:59 PM

Hi Manuel,

The "From" seems to sync up when I send myself an email.

I've got to leave for a little while, but will do some more checking when I get back.

Which gbSendMail settings were you using? Can you send me an image of what you used (no password, of course!).

**Gary Beene** · 8 Aug 2014, 07:11 PM

Manuel!
Thanks so much for the catch. Here's what I had done wrong (in the new Squires class code method) ...

Code:

   cMail.SendFrom     = sTo
   cMail.SendTo       = sFrom

The fixe has been uploaded (v1.21)

**Manuel Valdes** · 8 Aug 2014, 10:03 PM

Hi Gary,

Sorry for not answering in time. I tested it in my job office and then left to home. Many thanks for your nice work putting that code together, really useful. And many thanks for all your support to these forums.

Best regards,

**Emanuele Colombo** · 14 Aug 2015, 04:52 AM

Nice Job

Nice job, guys!
How I can request a reading recept when sending a mail?
Thanks

**Gary Beene** · 14 Aug 2015, 11:04 AM

Hi Emanuele!
Sorry, but I don't know the answer myself. Perhaps someone will chime in here shortly ...

**Pierre Bellisle** · 14 Aug 2015, 07:03 PM

Googling "mailer.ConfirmRead" and "mailer.ConfirmReceipt" may get you started...

Pierre

This looks cool...
Thanks

The only one I can get to work with GMAIL is Jose Roca's using port 465 and checking authentication and SSL in settings.
I don't think the others have the option to use both authenticate and encrypt in the settings.

GMail doesn't work here without lowering security settings https://myaccount.google.com/lesssecureapps

Is there a way to get Jose Roca's (or one of the others) to work without lowering security using GMail?

Found this link Authorizing Your App with Gmail

Keeps getting better
https://developers.google.com/gmail/api/auth/web-server

Created an OAuth 2.0 client ID and password using
https://console.developers.google.com under Creditials

Trying to figure out how to present the the ID to the Google SMTP Server.
I think once this is done Google will recognize the machine and security won't need to be reduced.
If anyone has done this, please advise.

Hi
Where do i get the 2 INC files from
Ian

**Frank Rogers** · 13 Jan 2021, 07:22 PM

Just a wild guess here... Are you missing CDOSYS.INC and OLE2UTILS.INC? If so, install Jose' Roca includes.
