I have been asked to investigate a problem with mail delivery to a number of students in our Google Apps for Education domain. A user sent a single message to 18 students. The log entries look like the following:
2010-12-14 11:06:04 1PSSho-0003J4-D9 <= [email protected] ... 2010-12-14 11:06:05 1PSSho-0003J4-D9 => [email protected] R=google_router T=google_smtp H=aspmx.l.google.com [209.85.229.27] 2010-12-14 11:06:05 1PSSho-0003J4-D9 -> [email protected] R=google_router T=google_smtp H=aspmx.l.google.com [209.85.229.27] : : 2010-12-14 11:06:05 1PSSho-0003J4-D9 -> [email protected] R=google_router T=google_smtp H=aspmx.l.google.com [209.85.229.27] 2010-12-14 11:06:05 1PSSho-0003J4-D9 => [email protected] R=google_router T=google_smtp H=aspmx.l.google.com [209.85.229.27] 2010-12-14 11:06:05 1PSSho-0003J4-D9 -> [email protected] R=google_router T=google_smtp H=aspmx.l.google.com [209.85.229.27] ... and so on. There is a single <= entry, but four => entries and 14 -> entries. What I don't understand is how a single message with 18 recipients can end up being delivered to the same destination host address in four separate connections. (I suppose one can't be sure which of the four connections the later -> entries are associated with.) Can anyone explain this for me. I am running version 4.70. Thank you in anticipation.
