Hundreds of e-mails being bounced back v.Mailer-Daemon
Hey Guys -
So, I’m working for an organization part-time…and we have recently been getting help desk calls about e-mails being bounced back, and being classified as undeliverable. There was recently a large amount of spam being sent from our domain, and I believe this has caused our domain to become blacklisted on places like Hotmail, Yahoo, Comcast, etc…etc. There are probably 10 or 15 different e-mail providers that are bouncing our messages back.
Our Sys Admin should be doing something about this, but he recently just quit…so our server guys have been overloaded with work (Trying to push out AD)
I was just wondering if there is something that can be done about this, rather than having to contact every provider individually to try and get them to unblock us…because we are a legit institution!
verify your MX is OK (domain trail in headers resolves and matches domain in "From:")
Check with blocking services and ask them to re-review your domain

blocking services, as in, spam filters?
You will have to excuse my ignorance in this subject matter..
Our company had the same problem. You (or someone) will have to call those ISPs and request to be removed from their blacklists.
Get yourself a PTR record in your DNS setup while you’re at it.
shitty story
I ran a test from mxtoolbox and found that our domain is not blacklisted by any global blacklists.
Looks like just ISP blacklists.
