Hi,
I am using mailgun as relayhost to sendmail. i also use the same relayhost on the webserver. now if on the webserver soemone fills out the contact form, i cant get mails on my mailserver from this webserver. the user peter@domain.com exists. I think its because the sender is using the same domain but doesnt exist in iredmail
