SMTP Connection LOCAL/outside

VenimK

UTM Ver. 9.412-2

 

Been playing around with SMTP Proxy and pop3 proxy
SMTP proxy works outside my localnetwork OK

Telnet mynoip.domain.com 587
or with mail client works

But when i try this this on a local machine it get.

telnet mynoip.domain.com587
Trying XX.XX.XX.XX...
telnet: connect to address XX.XX.XX.XX: Connection refused
telnet: Unable to connect to remote host

in mail client i've hve to enter the sophos IP, and can not use my domain name

 

Is this how it works, or am i missing something

    Here's the KB article you want, VenimK: Accessing Internal or DMZ Webserver from Internal Network

    Of the two methods discussed in that article, I also prefer the approach recommended by Louis and Kevin.

    When trying to connect remote i get ..

     

    telnet XXXXXXXX.XXXXXXmydomain.ddns.net 110

    Trying XX.XX.XX.XX...

    Connected to XXXXXXXX.XXXXXXmydomain.ddns.net.

    Escape character is '^]'.

    +OK POP3Proxy ready

    user XXXXX

    +OK

    pass XXXXXX

    -ERR Proxy: Can't connect to server

    I guess i have forwarded 110 to another port, but can 't connect at all then ...
    Are there any screenshots available, guess it would be easier then..

     

    The SMTP proxy works great local and remote.
