No, the argument is nothing to do with the left hand side of the
address, it's to do with the right hand side of the address.
"imap.iecc.com" isn't an email domain, but it might be one day.
"imap.sussex.ac.uk" is not an email domain, and it never will be.
In the case where the imap server host name does happen to be an email
domain, there's a potential name space conflict. ARF(_at_)(_dot_)(_dot_)(_dot_)
may well
already be
"Cnflict, ARF@" is the left hand side of the address. If imap.iecc.com
becomes an email address, then it would be a mistake to assign a user the
username of "arf".
Yes, you're confusing the two cases. Either the domain is already an email
domain (in which case a conflict is possible), or it isn't (in which case
you're asking for creation of an email domain merely to deliver abuse
reports). That then becomes a whole new domain without reputation which
spammers can abuse.
If a role account is assigned to
arf(_at_)poporimapserver(_dot_)example(_dot_)com then it
is a problem if that address is already assigned to a user. It isn't a
problem with no solution, though. Simply make sure that the RHS of the
address is different from the already assigned address. This is almost
always going to be the case for large providers, since machines for pop
and imap service are distinct from email domain names. If they do not, it
is simple enough to arrange DNS to make that happen, without changing any
hardware.
Perhaps another character string would lessen the objection on this
point. The role account could be "arf-submission", although the
anti-English crowd will complain. There is room for creativity.
Note that when I say "pop_or_imap" it doesn't really have to be
restricted to those protocols. The MUA can use the hostname for the
system providing incoming mail, without caring what protocol is actually
used, nor is there any need for the letters "pop" or "imap" to be requed
to be in the name. The TO: address ued for the ARF is simply the role
account on the system providing mail, that will use it to tune content or
other spam filters.
