To quote... : Well, the only thing that I can think of that would cause that are these messages: Oct 18 09:59:35 linuxbox sm-mta[8516]: k9IE9A9S006712: to=<blanchard_michael () emc com>,<johnson_neil () emc com> , delay=00:49:37, xdelay=00:00:11, mailer=esmtp, pri=11487292, relay=iris.emc.com. [128.222.34.15], dsn=4.0.0, stat=*Deferred: Connection reset by iris.emc.com*.

[128.222.34.15], dsn=4.0.0, stat=*Deferred: Connection timed out with iris.emc.com*. When the connection times out, then those messages get queued up. When a new message arrives sendmail will try again, which may succeed and then be delivered prior to the other messages that were queued because the connection is reset by EMC or sometimes times out because of the inability to reach their mail server(s). Also, doing a quick manual check on their mail servers listed in their MX record, only two of the eight (8) even connected (the others were connection refused). And of those 2, only one of them responded in a reasonable period of time.
