ok, thank you. ya I searched and didn't see anything about it being blocked but figured I'd ask to be sure
it's not blocked on our vps at least ;)
I've avoided looking into my email issues for 3 years, and figured I'd sit down and take a look at things that could be the cause of my woes. Alas, I'm still surprised the server even works but not being a pro, I'm terrified to change any settings on my server for fear of breaking my mail server lol
I realize it's not support to be asking here, but I just wanted to be sure there wasn't a network wide block on any ports I would likely be using by default
You're right to ask and many VPS providers DO block port 25 (and rightly so, IMHO).
