IP listed in hotmail/outlook block list
Anyone got your IP blocked by hotmail? I got it unblocked recently, but it's blocked again, and all mails sent to hotmail accounts are getting bounced.
Have a proxmox mail gateway for outgoing filtering and I do aggressive filtering. Quarantining all mails that have a spam score > 1. Have hundreds of mails going out to other domains (gmail, etc.) but it is only this Hotmail that sucks, even though mails going out to their domain is in the single digits per day.
Have SPF, reverse DNS PTR, properly setup for domains and the outbound mail server.
I have a personal hotmail account and the amount of 100% spam it receives is astounding. Something is not working with their spam filtering, it's blocking legit mails and letting in spam.
My server does not directly spam, but it's the wordpress comments notification that contains the spam messages. The notification going to the site owner also contains the comment body, which are mostly spam.
