Non-random addresses - community + customers + marketing + suppliers + webmaster

Hello everyone.

I have a chatmail server running at https://vinculum0.net/

I just looked at the mail directory - /home/vmail/mail/vinculum0.net/ , and there are five non-random addresses - community + customers + marketing + suppliers + webmaster

Are these created by the installation or has someone created these ?

Thanks.
Mark.

Addresses are created when someone logs in with the name and sufficiently long password, likely bots that try to bruteforce the passwords, likely to send spam. They log in and find nothing there and cannot use it to send spam because unencrypted messages are not allowed.

The reason these names are allowed to be created is that they all have 9 characters in there.

Thank you.
