For tracking down delivery issues, I love the SMTP header parser at http://mxtoolbox.com/EmailHeaders.aspx . It makes reading SMTP headers so much simpler and shows where the delay is very clearly. The biggest challenge is successfully instructing your irritated users to forward a message as an attachment to preserve the header.

I've had some recipients complain of receiving emails almost a day after it was posted. The interesting thing is that most others in the list received it within minutes.

Baffling.

Subject: Re: Anyone seeing Long delays in Messages being sent from Listserv?

I would seek the services of a 3rd party mass mailer who does this for a living.  We have both emergency and several informational email alerts for the different campuses which totals about 110K email subscribers as well as tweets and text messages for those who prefer those methods.

I am seeing long delays when a message is either send to a mailing
list with a lot of subscribers (1000+) and when there is a large
attachment (5MBs +) on a message.

I have concerned Administrators that are sending out important
emergency messages and they are arriving after the event that is
being warned about.
