I've setup postfix/dovecot with Sqlgrey and DSPAM on my mac mini recently. I can receive e-mails from my other accounts very well and spam filter also works fine. But the problem is, I cannot send anything using a smtp server installed on my mac mini.
Here's the error message from tail -f command.
Aug 23 16:26:45 Taris-MacMini postfix/smtp[597]: DAA8E61C2B4: to=<destination_email_address@gmail.com>, relay=none, delay=150, delays=0.03/0.01/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.43.27]:25: Operation timed out)
The same problem occurs even if I select other mail accounts such as me.com, naver.com, etc.
I've also checked my ports, but 25 was not blocked by ISP either.
I've opened ports: 25, 80, 143, 587, 993 on my router when I could not send anything. But I changed the Mac mini as a DMZ server which opens all the ports...
I use Noobproof: http://www.hanynet.com/noobproof/ to manually configure the firewall i nmy macs. It gives me more control on what's open or not and is more finegrained then the default panel settings in system preferences.

Hi,

Taris, there are several options.
Just to make sure you aren't blocked on port 25 and DNS is working properly:
ping alt4.gmail-smtp-in.l.google.com
ping 74.125.43.27
telnet alt4.gmail-smtp-in.l.google.com 25
telnet 74.125.43.27 25
or your ISP is blacklisted, check via http://www.mxtoolbox.com/blacklists.aspx

It seems 'ping' works fine but telnet isn't. It keeps showing 'Trying xxxxxxxx .....' but no change.
On the blacklist check, only followings showing timeout at this moment.

Telnet not working, then it looks like you are blocked. Try using the submission port 587 which is a known workaround for blocked ports.

Ack! now it works!
I've opened ports: 25, 80, 143, 587, 993 on my router when I could not send anything. But I changed the Mac mini as a DMZ server which opens all the ports...
I'm not sure it's a good idea though...
