Exim: disable smtp auth on port 25 and allow port 26

alshahad

Hello

I have a question if someone knows the trick. What I am trying to do is to allow only incoming mails by exim on port 25.

The plain smtp auth should be only in port 26 for example. SSL and TLS port no changes.
I am trying to do this because I am going to limit the IPs to access to IMAP and POP.. and SMTP to specfic IPs.
that is why I am trying to do this trick.

server_condition?

Anyone did it before? any ideas?

Thanks in advance

Regards.

Probably something like

auth_advertise_hosts = ${if eq{$received_port}{587}{*}{}}

together with

accept authenticated = *

in the RCPT ACL (but otherwise only allow local addresses in that ACL)
