Well, don't blame the ISPs, blame the spammers that made them block 25. Years ago when my ISP started blocking they sent out a nice letter, explaining why. I could live with that. FWIW, their Enterprise programs do have 25 open.
Well, Telefonica did not, and there are spammers everywere.
T-Mobile (USA) doesn't.
Mobile operators, tmk, don't really have any significant problem with mobile phones being hijacked and abused. (trojans).
Then it is not a real policy issue.
Policy? No, I don't think it is a policy issue, it's simply about an easy and practical way to prevent lots of spam being sent.
You only need to block relay use. Ie, nobody can relay without a password, no matter the port. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))
