I can't seem to get SMTP (from my email client) to work, I've spent hours searching the forums and looking through the guides but still stuck on it.
///EDIT:
The problem seems to be related to the self-signed certificate, because if I turn off SSL in my email client it sends ok... see this thread: http://forums.vpslink.com/howtos/8991-how-build-mail-server-into-link-1-...

It's a clean Virtualmin install (I haven't changed any postfix settings) and interestingly, I get the exact same response for my server when doing:
$ telnet virtualmin.com 25
Trying 108.60.199.107...
Connected to virtualmin.com.
Escape character is '^]'.
220 www.cloud.virtualmin.com ESMTP Postfix
((hangs at the above line for a few minutes, then..))

Is this default behavior and I need to turn it on or edit some configuration file first? (I had to turn dovecot on - so am wondering whether the same applies to smtp).
Thanks in advance for any help.
/////Edit 2:
I finally found a thread and got it to work using the below - have to test it with additional domains yet tho... does it look ok? (It was Eric's advice in another thread)
==============
POSTFIX SET-UP
==============
> vi /etc/postfix/master.cf
- Uncomment these lines:
submission inet n - n - - smtpd
-o smtpd_enforce_tls=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
Then restart:
- /etc/init.d/postfix restart
Then check port 465 is open:
- netstat -an | grep :465
Then:
- What you'll need to do then is choose one of your domains, and enable SSL for it.
You can do that in Edit Virtual Server -> Enabled Features, and check "SSL Website Enabled".
Once you do that, go into Server Configuration -> Manage SSL Certificates, and click "Copy to Postfix".
///EDIT3:
I set up an email for a different domain but unfortunately it does not work :(
I have to go to bed now though (it's 4 am eek!) - hope someone has some ideas while I'm gone.
////
///EDIT4:
OK, got it. Virtualmin does not allow more than one SSL site per IP so I couldn't create a new cert for the additional domain (wonder how cPanel gets around it? (They provide a cert per domain)), however you just need to set the outgoing mail server as mail.the-domain-with-the-cert.com and it should work fine. Wonder if there are any gotcha's tho?
