Hello,
after some network update i'm lost in configuration.
I updated my internal network configuration last week.
i have a website that sends notifications to customer and i use our mail server as a bridge to the outside world to be spf compliant.
My website was compromised and start to send some spam, so i prefer that iredmail is checking the messages incoming and outgoing.
In the transport file of the web server i configured the nexthop.

The problem is that if don't put the address of the webserver into the mynetwors field i'm unable to send any notification.
and i get this on the webserver

(host mail.somedoma.in[ip.ad.re.ss] said: 454 4.7.1 <xxxxxxxxx@gmail.com>: Relay access denied (in reply to RCPT TO command))

and og course a relayng denied on the mail server.

Any advice or adding the numer into the mynetworks field is safe?
