I've been having trouble having my work messages received, when I send them from my home.<br />
<br />
I have a Comcast account, and send regular e-mail through smtp.comcast.net. I use Thunderbird as the client.<br />
<br />
However, I have been noticing that some people are not receiving my e-mails at all, not even tagged as junk.<br />
<br />
I ran some tests through the EmailReach analyzer service, and according to that report, SpamAssassin thinks I am sending e-mail through an open-relay, and my floating IP address is in SORBS.<br />
<br />
Would this explain it?<br />

Work e-mails not getting through when send from home

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
