Hello, I have an FC3 machine that has been running about a dozen websites and 3 dozen mail accounts reliably for more than a year, I stopped updating about 6 months ago so the versions might be a bit stale but I would prefer to fix my immediate problem(s) rather than update and cause new ones. The software I am using that is in question, I believe, is Sendmail, Dovecote, Procmail, ClamAv, Spamassasin,and Squirrelmail. The problem - email into my personal account "bob" @ many different domains seems to have stopped a few hours ago with the message "Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 9): 550 5.7.1 <bob@domain>... Relaying denied. Proper authentication required." The log file says - Apr 6 11:05:59 myserver sendmail[5580]: k36A5wFQ005580: ruleset=check_rcpt, arg1=bob@xxxxxxxxxx, relay=zproxy.gmail.com [64.233.162.192], reject=550 5.7.1 bob@xxxxxxxxxxxxx Relaying denied. Proper authentication required. Apr 6 11:05:59 myserver sendmail[5580]: k36A5wFQ005580: from=<rbrennan96@xxxxxxxxx>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=zproxy.gmail.com [64.233.162.192] And there are suspicious emails queued in Sendmail such as: Thu, 6 Apr 2006 10:17:15 "Bob Brennan" <bob@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>bob@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx kBDeferred: Connection timed out with wc.funnel.revenuedirect.com.akadns.net. The obvious clue for me is the "wc.funnel.revenuedirect.com.akadns.net" that appears to be the culprit, but it has been too long ago that I considered myself a Linux expert to remember where to start on this type of thing. Wiping the machine and starting over is not a good option, and yes I had rsynced everything important to an FC4 machine only hours before this happened. Any clues as to where to start looking please? Thanks in advance, bob
