ATT SMTP port 25 unblocking
-
I was trying to set up mail for my server, to send status emails, gitlab emails, etc. I know this can be done with relays but I was interested in sending mail directly using SMTP. Apparently my ATT residential internet blocks outbound signals on that port by default, although there are several reports of people calling customer support and getting that changed.
The most recent thing I can find was someone on Reddit 3 years ago:
xnojack: Probably depends on the rep. Just got mine unblocked a week ago. I read online though its better to say you're looking to allow SMTP outbound rather than port 25 outbound. Cause on the reps end its called something like SMTP outbound filter. (link)
I tried to call in and get this changed, the rep was very helpful but either something's changed on their end or he was looking in the wrong place. Anyways, I was wondering if any of you have gone through this process recently and know if this is still a thing, or have any advice.

@AdrianTheFrog blocking 25 port is a standard policy.
Buy static IP (subnet actually) or ask support to remove all firewall rules (I had to speak with many of the support personnel until found someone who knows how to do).Ended up with using a separate VPS for mail server as my att ip was in blacklisted)
