[Pc_Support] Email Troubleshooting

[J.T. Hayden]

Sounds like a filering peer issue, if they are not "peered" correctly
there is a lag in the send/receive of the mail (they are sent to the
bottom of the send/receive que) plus any spam/virii checks at that point
are delayed also slowing delivery

Subject: [Pc_Support] Email Troubleshooting


I'm having some email trouble when users are sending mail between two 
domains and am looking for thoughts on how to troubleshoot and resolve 
the problem. Here's the situation:

There are two domains which are hosted by two different ISPs who also 
provide the email services for each location. When anyone at domainA.com 
sends an email to anyone at domainB.com it can take hours or even days 
for the message to be delivered.

anyone at domainA.com can send emails to other domains and they are 
typically delivered within seconds/minutes.

anyone at domainB.com can send email to anyone at domainA.com and it is 
delivered withi seconds/minutes.

These big delays only occur when email is sent from Domain A to Domain 
B and, as far as we can determine, not any other time.

I'm not familiar with the ins and outs of email systems, I'm just 
looking for things to check and the right questions to ask the 
providers. Of course, initially oth ISPs have said "everything is okay 
on our end".

Fixing this is somewhat of a priority--one of the company's owners is 
at Domain A!

Thanks in advance for any pointers.
