Hello
I was using Exim 4, in office (differents sites) but I was using vsat system
for interconnecting sites. I put private adresses to configure exim in
differents sites.
Since I published my servers on internet, I have this kind of error message and
i cannot send mails. the message is : RELAY NOT PERMITED
Need some advices please
Three reasons:
A) you check for a valid SMTP-AUTH on the server and did not use it in
your mailclient's config.
B) you made a typo in one of your local domainnames, you want to send
mail to, so exim "thinks" it shall send it to the external domain and
requests SMTP-AUTH for it ( --> A ) to avoid beeing an open relay.
C) you forgot to change your relay_hosts entries to you new IPs ( maybe
a typo )
A+B are very common problems.
best regards,
Marius
