Re: : ISP filtering port 25

Talking to ISP support is useless. Google does a better job at providing
a solution.

Anyhow, I found a solution to my problem. It was as simple as telling
postfix to listen to port 465 with sasl authentication. Port 465 is not
filtered. Now I can send email from any port  25-filtered network.
