to email order information. We just changed email hosts, and although I entered the new host information, we can only email to addresses within our own company. Emails sent to other addresses are not going through. What do I need to change in order to email out?

Most likely the issue is on the mail server side not in the program. The SMTP server is probably blocking via the Anonymous Relay rule. Your mail Administrator should be able to grant access based on IP to relay to outside addresses.

Go to http://www.powerbasic.com/support/pb...ad.php?t=39594 and see if that might help.

If I read your problem correctly you are changing the server name in gmailhost$, with your code this should never change, always being the name of your local mail server. Your mail server will then correctly comunicate with the server for the "To" address. If you attempt to go directly to the other company server then it will deny it as a relay like spam.
