  Hi,

I have just setup qmailtoaster and having some problems with outgoing mail on SSL. Using Outlook 2003, I am able to setup IMAP-SSL and connect and read my e-mail.
(installed the servercert.pem key within /var/qmail/control)

I can't however send mail using port 587 with SSL enabled.
Outlook returns after some time with "error 0x800CCC7D - SMTP server doesn't accept SSL secured connection" When I remove the SSL switch for outgoing mail in Outlook (still using port 587), mail goes out without problems.

I've read the wiki article "SSL on submission" (http://wiki.qmailtoaster.com/index.php/SSL_on_submission_port)
Has anybody used this 'workaround' on Outlook? (not OE)

Thanks and regards,

John

Thanks go to Aleksander, but I don't think the page he referenced is going to help you.

I don't believe that Outlook'03 can do STARTTLS, it only supports an SSL connection. (FWIW, Outlook'07 does support STARTTLS.) While both methods of encryption use SSL, they are initiated in different ways. I know it can be confusing. Let me try to explain.

STARTTLS can use any unencrypted port. It is a method by which the session can change from unencrypted to encrypted on the fly.

Traditional SSL, on the other hand, requires a dedicated port, the entire contents of which are encrypted. That's why you see a 2nd port for imap4-ssl, and pop3-ssl.

There is (was at one time not so long ago) also an smtp-ssl port (ssmpt 465), but this has been deprecated in favor of STARTTLS. I expect that other SSL ports will also be deprecated in the future as STARTTLS capability becomes more commonplace, but that's just my opinion.

I haven't seen the patch to which you refer, but I expect it would work. However, it would also require all clients using that port to use SSL (using STARTTLS on an SSL port would be redundant if it would work, which I expect it might). If you decide to try this, I would use a separate port if it, like 465. ;)

After having written all that, I think I found your best solution here:
