Title: SMTP from internet in server mode
Post by: gmoney on February 17, 2006, 06:25:03 AM

Hi... I just installed SME7pre3.  My server only has one interface, so I used "server" mode.  This server has a private address that is being statically NATed to a public address via our internet router.  I managed to configure it so I can SSH/HTTP from the internet, but I cannot get an SMTP connection.  It seems I can only connect to port 25 from the private LAN side.

I want to open this up so it accepts mail from internet.  Do I need to add a second interface and switch to "Server/Gateway" ?  Or is there some way to accept smtp connections from anywhere ?

email clients will need to use these ports.

465 - SMTP over SSL
993 - IMAP over SSL
995 - POP over SSL

You must also enable

E-mail settings
POP3 server access    Allow private and public (secure POP3S)
IMAP server access    Allow private and public (secure IMAPS)

and

SMTP authentication    Allow SSMTP (secure)

Thanks for the reply.  I am sorry I was not clear.  I want to use this SME server as the MX for my domain.  Thus, it needs to allow connections to port 25 from the internet.  Is there a way to make it allow connectoins on port 25 from the internet in "Server only" mode?

It does. That is how I use it.

E-mail retrieval mode    Standard (SMTP) 25 - smtp

Thanks for the guidance!  Turns out that our firewall was blocking port 25 (duh!)
