My wife's MacBook has suddenly lost the ability to send mail through Mac Mail. Everything worked fine until today. Now, the Activity window shows a connection to the outgoing server, but Mail returns a "could not send" message with its options to switch servers, etc.
This is not the common problem with an ISP blocking the port. Let me explain the testing I've gone through:
I have set up an SMTP server in Mail for my ISP (Comcast) with all their specified settings. I have also set up a connection to my own SMTP server, through a very uncommon, unblocked port. Using Mail on the MacBook, none of these work.
However -- the same SMTP settings work on another Mac on the same network. The same SMTP setting work properly from a PC on the same network.
And to make it completely weird, I can fire up VMWare Fusion on the first MacBook and send mail through Outlook Express. So from the same machine, mail can be sent from Win/Outlook Express, but not from Mac Mail, using exactly the same account settings, servers, and ports.
Has anyone ever seen anything like this? I haven't.
Thanks in advance for any help.
Tom
