What is the limit on the number of recipients that Comcast will permit. Many
ISPs restrict the number to 50. Some ISPs have a different set for those
with fixed IP addresses and a commercial account. Specifically, mine will
allow 300 during the day and 1,000 after 11:00 p.m.

Thanks for the quick reply. I am working on getting a second level support
person engaged. I don't know what kind of mail servers they are using, but
I'm hoping they are able to look at server logs to first determine if the
message was received by their servers or not. I'm wondering if some server
mail filter is deleting the messages? I can't repro the problem at will
and it happens with random messages, but I can usually repro it with a
couple emails per day. Again, I still suspect Comcast, because when an
email gets lost, 100% of the recipients do not receive it. I would really
like to find out once and for all if the message really leave their
server. I suspect not. Come to think of it, I should also point out that
if I'm on the to or cc line of the problematic message, I don't even get
it, even though it was sent to myself. I believe this eliminates other
devices between the Comcast servers and the recipients.

transport issues.

Yes, based on the log, the message was successfully accepted by Comcast.
However, keep in mind, it could have lost its way in many more places
than just Comcast.

I would personally tell the Comcast support person that you have a
network packet trace showing their server accepting the message and that
you would like to speak to a second level support technician if they are
not able to help you with the problem. But, again, it may not be their
problem. If you can readily reproduce the problem (ie, a certain message
always disappears) then they should be able to see the message come and,
theoretically, go out.
