Hello,

Outgoing emails from Outlook 2007 intermittently do not reach their
recipients. I'm no email expert, but based on my OPMLOG.LOG file, Outlook
seems to successfully send the message to Comcast's mail servers using SMTP.
I'm having a really hard time convincing Comcast to look into this and they
keep pointing fingers back at Outlook. I do not believe Outlook is at fault
and I strongly doubt that the problem is with the recipients ISPs, as none
of them gets the problematic emails and they are on different domains
(aol.com, microsoft.com, hotmail.com). The emails show up in my sent folder,
there are no bounced messages and my outbox is empty. Also, typically, if I
resend the email, it makes it the second time. I suspect the emails are
being deleted/filtered out by Comcast's mail servers. So first off, I'd like
to have someone confirm that, based on my log file below, the email really
did successfully leave my client. I've also looked at a netmon trace of
this, and see no transport issues.
