The problem is, there are several reasons why this can happen, i'm
guessing based on that router  you are using pppoe/NAT , so your sendmail
may be lying about it's IP address, aol will definitly disconnect rudely
if you do that...DNS failure will also cause sendmail to send back an
error (user domain doesn't resolve) which will cause the sending server
to rudely disconnect...bogus reverse DNS records will also in some cases..

Of course, you may just be getting a lot of spam ;0

Or you may just have spotty connectivity...


You will probably get more info telneting into your mailserver from
outside to see how it signs on...
