Re: Allow insecure SMTP connection on port 25 only for one mail acount

Is it possible to use other port number with insecure connection? If yes, check this tutorial:
https://docs.iredmail.org/additional.smtp.port.html

If you HAVE TO use port 25, and allow insecure connection, check this tutorial (you can just apply the Postfix related changes):
https://docs.iredmail.org/allow.insecur … tions.html

WARNING: it's better not use port 25 for smtp auth.
