Okay, I'm lost.
I host primary mail server for a client that runs an e-Smith box.
For quite some time now the e-Smith box has collected mail just fine from my server (NT).
Now I have migrated to a Linux box.  I see a succeful log-in for the e-Smith box to collect mail, but it never collects it.  I cannot find in the e-Smith logs an indication of what is going on.  I look in messages and in maillog.
Where else should I be looking?  If I use a mail client I can get the messages fine.  What's the difference as far as my mail server cares whether it is M$ Look Out, or e-Smith's install of fetchmail.
