Zimbra and Thunderbird port

Postby uuamandar » Thu Feb 06, 2020 3:12 pm

Why can't I send emails using thunderbird when I connect to my zimbra server using the port 587?? but if I change it to port 25 it works. Someone knows? I want to use port 587

What configurations have you tried with port 587? This port requires authentication and TLS.

Best regards.
