If my users have usernames of the form
firstlast within my
example.com domain, is there a way to get exim to correctly deliver to them whatever the number of dots put into the address? This is a feature that Gmail has.
firstname.lastname@example.org email@example.com firstname.lastname@example.org
are all delivered to
email@example.com, the last with its tag preserved for filtering.
Ideally, I'd like to be able to normalise outgoing email from these users to have the form of dots that they select (also a feature of Gmail) so that their mail will always appear to come from firstname.lastname@example.org if that's what they select.
