Hello Gary, Just a quick reply - I looked in /var/log/mail.log and spotted the following line that came up loads in the log file:
Jan 31 17:48:12 destiny spamd[15602]: prefork: syswrite(6) failed, retrying... at /usr/share/perl5/Mail/SpamAssassin/SpamdForkScaling.pm line 554. This might be my problem? To answer most of your questions: > Does your system reject mail to invalid users so spamassassin does not get > pounded by dictionary attacks? Should do: [EMAIL PROTECTED]:/var/log$ telnet localhost 25 Trying 127.0.0.1... Connected to localhost.localdomain.
