Rockdalinux/Tom,

Thanks very much for your help. Your suggestions fixed the glitch and everything is working wtih postfix and squirrelmail.

Is there anything I should/can do to my postfix configuration to make it less vulnerable to spammers, etc?

Now on to configuring spamassassin and clamav.

Will report back on progress.

Update: Spamassassin and ClamAV installed. Testing soon.
