Anyone else here using their own SMTP server on a regular basis?

@woozle yes, to a degree.

@oliof I'm partly trying to build up a network of fellow email-admins for problem-solving, but the immediate issue that made me start doing this is:

Have you had any occasion to send email to msn.com, or any other Microsoft-owned domain, lately?

It's now claiming that my IP is blacklisted (and refusing to deliver my messages) & won't say why. Prelim investigation suggests that nobody else is blacklisting it.

I spose I should check other blacklists... but... moreinfoplzMS?? :-P

@woozle that's the reason I use my own mail server mainly for receiving mails from non-person-entities, but send using gmail /-:

Dealing with random blacklisting is frustrating, especially since mail providers sometimes blacklist you if you come from a consumer IP range and/or have something in your config they deem "wrong".

And often the large providers do not give you info on what's wrong because they do not want to tell spammers how to build a legitimately looking service.

@oliof ..said behavior being virtually indistinguishable from "trying to force people to use major services for email" :-P

I guess this is now an open request: has *anyone* been able to successfully deliver email to a Microsoft property from a small server recently?

@schestowitz Has anything about this appeared on your radar?
