Troublesome Mail Forwarding Latency

[KenCarlson]

Has anyone else out there noticed an intermittant latency problem with the mail forwarding features?

For example, I have saybrooke.org hosted with PowWeb. From an external pop/smtp account (my ISP) I sent an email to "Ken.Carlson@saybrooke.org" at 10:37am EST. I have a forwarding alias set up to forward such messages back to my ISP pop account. I finally received the message at 12:32pm EST (nearly 2 hours later).

Examining the message headers in detail, the lag is definitely at the PowWeb server... specifically, a one hour fifty five minute lag between received at mail.powweb.com to the time it was received at my ISP's server.

I do not experience this problem all the time, but this is twice now (both times on a Saturday when I had time to play around and notice these things). The other time was when I noticed a HUGE latency with the /usr/sbin/sendmail function that my mail form processing script uses. In the end, all test messages (sent vial the web form) were received, but there was about 7 hours delay.

Starr, perhaps this is an issue that you or your technical staff can look into?

As I said, this is an intermittent problem. As of 3:10pm EST, everything is working fine again.

Hmmmmmmmm

[Starr]

Hmm, we made no changes. Keep me posted please.

Our mail servers and our webservers both use completely different MTA's... The webservers use sendmail, and our mail servers use postifx. The webservers have the default setup for sendmail, no changes have been made to them what so ever. It might have been delayed on our servers because of problems connecting to the destination SMTP server. This could be either a network problem or a problem with the server itself. The fact that you get the messages, that it is intermitent, and that we do not have this problem with other people (that I am currently aware of) would lead me to believe this is a problem we have little control over. I will look into it a litte further though and notify you of any problem I might find.
