IMAP/POP3 processes with numbers as users

[albatroz]

Recently I tried the ps aux command in my server and noticed some imap and pop3 commands with linked to numbers as users. As you can see below.

549 12903 0.0 0.1 43528 3416 ? S 13:00 0:00 dovecot/imap
525 12904 0.0 0.1 43512 3380 ? S 13:00 0:00 dovecot/imap
525 12911 0.0 0.1 43524 3548 ? S 13:00 0:00 dovecot/imap
549 12915 0.0 0.1 43512 3400 ? S 13:00 0:00 dovecot/imap

Do you know why?

These are standard processes to be running on a server with mail services. cPanel uses dovecot as the mailserver and IMAP/POP3 are protocols that are by default enabled.
