[TriLUG] Email issues

What was the text of the message bounce? That would help quite a bit.

Hi All,

I know this may not strictly speaking be a Linux question so I beg
forgiveness in advance, but I'm hopeful someone will be able to point me
in the right direction.

I'm having trouble sending email between 2 accounts I look after.

One is a domain on a dedicated server (Redhat+Plesk (qmail) ), the other
is a shared/managed hosting account (cPanel) at a completely different
provider.

Wehn I tried sending email in either direction between these 2
particular accounts, the email stalled for 4 days then bounces. Both
accounts had no trouble sending/receiving with most (all?) other MTAs

I noticed SMTP on the dedicated server was very slow (20-30 sec delay)
to accept email from my desktop client so I turned off the reverse-DNS
lookup it was doing. This helped the speed at which I can send email out
through it, but didn't improve the 'connection' to the shared/managed
account.

After a long investigation and no resolution found, the shared hosting
provider moved my managed account to another of their servers, and I was
then able to send/receive email with the dedicated server.
However the client on the dedicated server reports they have the same
issue with a few other (important) contacts.
Unfortunately moving my managed account also removed my test-bed to
track down the root cause (but I needed my email fixs!!)

Has anyone seen similar issues and/or have suggestions as to what the
underlying problem may be?

Simon...
