AOL and Comcast blocking mail


#1

I am wondering if anyone else is having problems with being blacklisted by Comcast users, as well as the AOL problems already posted earlier. The strange thing is…is that it is not everyone’s email from our site that can’t send emails to either. IE

I can send an email from me@mysite.com (sending from tucson, qwest.net, macintosh)

martin@mysite.com (in houston, time warner, pc) can send to both

michael@mysite.com (atlanta, comcast, macintosh) is blocked by aol but not comcast

john@mysite.com (florida, comcast, macintosh) can’t send to aol or comcast

monica (florida, comcast, macintosh) is in the same office as john and can send emails to both.

We noticed two things…the following are the only two that are listed when emails don’t get through
kungfu.dreamhost.com for AOL
randymail-a8.dreamhost.com for comcast

I don’t really know if this is a dreamhost issue…or a personal computer issue. could it be an isp address?

below are two samples of the aol bounce and the comcast bounce.

I think it is our goldmine server that we use. we send our emails through it…it’s ip may be what is being blocked.

update: yes, our goldmine server has been blacklisted. so…this is not a dreamhost issue.
