Abstractio of Dovecot Users

[Marek Paśnikowski]

Dear all.

I recently completed the monumental project of self-hosting my email on Guix, 
all by myself. I am now thoroughly exhausted, but need to complete one final 
task.

I am currently having the mail delivered to my user account directly, but this 
is not I want.  I need to abstract email accounts from system accounts to 
prepare for future transfer to a dedicated server microcomputer.

I would like to ask you, which dovecot service configuration parameters should 
I look at, for declaration of what I have seen on the net named “vmail”.

My immediate goal is to declare a dedicated inbox for DMARC reports and a bunch 
of aliases for 'marek' mail account, stored separately from the system's 
'marek' account.
