Emails not being delivered to comcast.net accounts
I run a mailserver(postfix) and emails are not being delivered to comcast.net addresses when i route the @comcast.net email through this mailserver.
The sending domains may be different from the mailserver domain name. I have defined spf records for the 4 sending domains that route traffic via this mailserver.
Can someone from comcast please help as it is affecting my clients. I am also a 14+ year comclast client. I can see the problem with my own personal email address and email's not being delivered.
Thank you and please let me know what additional information i need to supply.
The mailserver is at vps2.mdspc.com.

It looks like it's going to be related to your IP being flagged as "dirty". I've requested this be reset to a good reputation.

Posting my own solution in case anyone else runs into this issue. It is a kludge but it works.
i routed mail via my mailserver for @comcast.net accounts to smtp.comcast.net on port 587 while including username/password authorization from my comcast.net account and now the emails are being delivered successfully.
There is no logical reason i should HAVE to do this as comcast.net addressed emails sent to comcast.net's publicly published MX records should be either delivered or bounced (neither was happening!) but at least this solution seems to work.
It would be very helpful to know from comcast why those original emails just disappeared without any trace or bounce but now less urgent.
