First, please clean up your postfix configuration, looks like you did some custom settings there. Also it looks like the really interesting parts of the log output are missing or been verbosity filtered. Looks like you wanted to slow down mail sending or tune something /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: dovecot_destination_recipient_limit=1 /usr/sbin/postconf: warning: /etc/postfix/main.cf: unused parameter: maildrop_destination_concurrency_limit=1 However, unused means not used. Warning means one line of log file wasted and some errors after this cut been cut by some piece of software thinking "n" error lines are enough to display
OK, in main.cf I commented out the following lines. I get no warnings when I restart postfix now. dovecot_destination_recipient_limit=1 maildrop_destination_concurrency_limit=1 maildrop_destination_concurrency_limit=1 However, when I go to log in to Squirrel Mail, I still get the Connection refused 111 Can't open SMTP stream error.

Are there any hints in your syslog? Did you by accident install another smtp-server like exim? What's $netstat -tap saying after attempt to send from squirrelmail? Does a $telner yourserver 25 work after attempt?
