Setting up email services correctly

[Volt31]

I have got a few websites onto my system and now I am setting up email. I have tried creating new users and then logging into their webmail and it says it has sent outgoing emails but nothing arrives in the recipient’s mailbox (I have checked Spam).

SYSTEM INFORMATION
OS type and version	Alma Linux 8
Virtualmin version	7.7

When I installed VM, I didn’t have my domains operating since my previous host went down. When it asked for a qualifying domain, I used srv1.virtualmin.com to do the install so in webmin it lists the mail servers as srv1.virtualmin.com, localh…

Can you post mail log when you send, you should have no issue sending to a user on the same server as long as you have enabled mail.
