Hello,
We have a postfix gateway server that does some spamchecks. After that, the mail is relayed to the real server with the mailboxes, DirectAdmin and so on.
Normally I'm not a person that makes an issue of 550 no such user here messages, but with more random mail to random mail addresses, it is very annoying. Some days it's that much, it's causing problems with blacklists and mail reputation.
What is the best way to prevent this? Or to disable this behaviour in Exim or somewhere in the mail settings of users is DirectAdmin (for all accounts).
