Hello ^^)
I'm new to postfix, so please be patient ;)
here is the problem :
I have a server with real FQDN and SSL certificates, auto-hosted that
I'm setting up, based on Debian 10 base, with ufw firewall, webmin and
soon a commerce enabled cms and more.
all emails for that FQDN are handled by an external host (registrar).
problem is that despite all the tutos I can read / use I can't get
Postfix to send any mail from that server to the outside. using SSL ot not.
'till now all sent mail from the server to anyone@myserverdomain are
just sent to the internal server mailboxes or just 'disappear',
sometimes I get the 'user unknown' message as reason why in the
/var/log/mail.log despite that emails are real and exists on the
external host.
all sent mail to anyone@anyotherdomain don't get to their destination...
with that situation my cms will never be able to send emails to customers...
what I want is :
- sending mail from my server to any destinations, including the mails
to MyDomain.com addresses (webmaster@mydomain, contact, admin, etc), so
destinations and I can retrieve it with our preferred email software
(here it's Thunderbird)
- receiving mail by the self-hosted server aren't necessary as it are
handled externally. so send out only postfix is preferred.
- server sent mails must be done on SMTP secure ports 465, 587 and none
from port 25.
How can I edit the main.cf file and ufw rules so I get what I want from
my server ? (all that tutos I've found yet on the net haven't helped me
at all... and I'm blocked on the postfix mail server)
Thanks a lot by advance ^^)
