Re: Email Delivery Problems

The Comcast residential TOS prohibits servers at all so even if you can use
their mail servers as a Smart Host you'd be violating the TOS.

And, it can even happen with a static IP. Blacklists have very long
memories. One of our SBS sites had to get a new Verizon IP, in a
different range, because the old one "use to be in a pool of dynamic ip's"
when that range was owned by AllTell.

I have no direct experience with this, but perhaps it would work using
this setup if Comcast would let you use their servers as a "SmartHost".

A Comcast residential account has a dynamic IP and there are many
blacklists used by receiving mail servers that won't allow messages
originating from those IP addresses. If this is truly for a business it
would be better to get a service that provides a static IP.

Actually, it was just using the reply within a craigslist posting,
surely
they allow you to reply to themselves.

Probably
because of the subject line which can be filtered as being SPAM.

I keep getting the following message when I send to various
recipients.
Not all outgoing mail has problems, but a lot of it does.
SBS using Comcast Residential service on a double NIC, smtp, dns.
Mx and A records checked and verified. (getting most mail through)

Anyone able to translate this for me or send me in the appropriate
direction
to solve these delivery issues. It seems the delivery problem is
"with the
recipient's email" but I am getting a LOT of these and wonder if the
trouble
is on MY end.
