Below is a normal looking postfix SMTP connection for incoming mail (mine
has amavisd; you may not see some of these lines).  Notice that the qmgr
line does not appear until after a few smtpd lines.  You say you grepped
/var/log/maillog.  How about cracking that sucker open and seeing what
other log entires are there?  It seems like you'd have to have a "connect
from" entry a few lines before the one you found.

If you have the luxury, the surest way to troubleshoot SMTP issues is with
telnet.  If you can prove that it is possible to send an email in this way
from the client's location, then the problem is with the client's MUA. 
(If your postfix requires TLS, you will have to generate a STARTTLS
string; you can do this with a perl one-liner.)  For instance, I've seen
where the Mac-bundled MUA doesn't deal with TLS worth a crap, at least
when a self-signed cert is involved.  This results in the connection being
dropped (or hanging?) before the point where STARTTLS is normally issued.

Just for fun, type "mailq" just to see if the email is sitting in you
local queue.  This is highly unlikely, but what the heck.

Couldn't hurt to make sure that the IP address of the client isn't in
/etc/hosts.deny.  Perhaps you're running denyhosts, and they tried to hack
you in the past.
