mail.com recently had their outbound servers listed on Spamhaus for the best part of a week.

I noticed as a mail.com user was trying to email me and the message was being rejected, saw the spamhaus listing in my logs. Asked the sender, and they said that their messages to gmail were going into spam too.

I emailed postmaster@, support@, sysadmin@ etc. to try and inform them, as well as trying two contact forms; never heard anything back and it took several more days for the listing to disappear.
