Thanks

Check the settings for your SMTP server.

POP3 server is receiving.
SMTP server is sending.

some require smtp verification for send. Try checking that box.

also, I've ran into an ISP issue with a couple client recently, where the ISP started blocking port 25. Switching it to 26 solved the problem.

That worked thanks. But why is port 25 blocked?

tcp Port 25 would have been blocked by your ISP to get a handle on spam. Blocking would help prevent users from sending outgoing mail via third party hosting services.

Port 25 blocking by ISP's have now become the norm. Ideally your ISP should have informed you of the same. Port 25 bloackades are an effective antispam measure. Shouldnt bother much since easy workarounds are there.

yup, my experience with 3 ISPs out here is that they are not notifying and in fact, when I've called support they don't know what I"m talking about (One of these was Comcast which is a huge provider out here). I had to figure it out myself, which is fine...but yea, they should tell us, dontcha think?
