Hello. I am new to mail. Here I made mail using mail-in-a-box and a couple of questions arose.
- I made a server on vps digital ocean. They are blocking port 25. Do I understand correctly that I need to reconfigure to send emails through port 587?
- When I connect with the thunderbird client, it enters the outgoing port as 587, but when I send an email in the /var/log/mail.log , I see the message:
connect to gmail-smtp-in.l.google.com[64.233.166.27]:25: Connection timed out
Again, port 25. Is this how it should be?
