<DIV>Mark is (as usual) correct in his guidance... You may have your
mailscanner/postfix logs split into separate files (yes, that is unusual,but
has happened in the past:-)),so be sureto findyour Postfix rejections etc in
the maillog, so to be sure you get all the possible NOQUEUE: things.</DIV>
<DIV>I've been running pflogsumfor years, to get some readable stats on all
that, even posted a few scripts for presentation purposes back inthe days...
Something like that may make your searches easier (well, grep is pretty
easy:-)).</DIV>
<DIV><BR></DIV>
<DIV>But it is likely tehir system that is acting up...</DIV>
