Dear Webmin users,
I have moved to Webmin few months ago. I had problem with mails being delivered through MTAs but reading through forums, I found out that I had to run saslauthd. Ever since everything worked smoothly. Few days ago when I added a new domain to the server,
relay access denied problem began to appear again. The problem is that some domains can send mails without any problem but the last added domain can not send. I have checked postfix configuration against what is recommended on forums and, if I don't skip anything, configuration is ok. However, that last added domain is making me headache and the customer keeps complaining.
Would you guys help me to solve the problem, please? I will highly appreciate any help.
