Thanks for the tip!</FONT></SPAN></DIV>
<DIV><SPAN class=869582317-12072002><FONT face=Arial color=#0000ff size=2>Yes
the webmail program is on the same machine. And webmail was sending mail fine at
the time sendmail refused mail sending from email client
programs...</FONT></SPAN></DIV>
<DIV><SPAN class=869582317-12072002>>The next time it happens to you, try to
list the listening sockets, and <BR>t>he processes ... I'm sure it will help
you to diagnose the problem! :) <BR><FONT face=Arial color=#0000ff

<DIV><SPAN class=869582317-12072002><FONT face=Arial color=#0000ff size=2>You
mean run the "top" command i suppose. Right?</FONT></SPAN></DIV>
<DIV><SPAN class=869582317-12072002><FONT face=Arial color=#0000ff size=2>But
how and why would sendmail refuse to listen on the port. DOS attacks wern't
present at the time either. Nothing suspicious was happiening during the time of
failure. cpu was at 7% 1GB of memory had 25% free, maillog was calm (tail -f
maillog).. Problem is, to be able to catch it, I must be here in the wee morning
hours with toothpicks holding my eye lids open.. seems to occur anywhere between
11pm - 7am.. I thought it could be a cron job affecting this, but there isnt any
problems of any runaway processes going on either..</FONT></SPAN></DIV>

program (that I suppose it <BR>was running on the same machine) was still able
