I'm trying to figure out where ISPC3 puts the users emails and why. I can see something in both /var/mail/ and /var/vmail/ but neither does not seem to have all the email clients. What is the stuff in /var/mail/ ?
ISPConfig uses the /var/vmail directory for all ist email domains and users. Thats not from ispconfig. I guess this is email for Linux system users that dont have a mailbox.
Looks like those mails are replies to emails the website has sent. Mostly error messages. 'Message was not delivered... etc."
