Sometime Monday night my ISP closed Port 25 to any SMTP server but their own. I understand that this is a common practice among ISPs to try to reduce spammers' access to email accounts (worthless though it may be). Anyway, I have many email accounts using many SMTP servers. I can send all my mail through my ISP's SMTP, but it has some reliability issues so I'd rather use different ones. The ISP's tech support site doesn't allow Mac browsers (that alone would get them dumped if there was any competition for cable tv) and the 1st tier tech support people are totally clueless. Does anybody have any ideas on ports/techniques to get other SMTPs to work? I've tried SSL on port 465 and authenticated on port 26 with no success. I heard these might work. If it matters, my ISP is Charter and I use Mail.app.
