I have a client who purchased the .com, .net, and .org versions of his desired domain in order to capture visitors regardless of which tld the visitor enters.
I have no trouble re-directing actual web traffic to the desired "primary" domain (.com), but the client also wants to ensure that email sent to one domain is directed to the appropriate user at the primary domain.
For example, email addressed to email@example.com would automatically redirect to firstname.lastname@example.org, and emails to email@example.com would similarly be redirected to firstname.lastname@example.org.
The hosting company I'm using says that I'll need to create email forwards for each user on each secondary domain back to the actual mail account on the primary domain, but that seems kind of silly for what, to me, isn't a strange use-case. I guess it seems silly to me because on a previous host I was able to forward *@example.net to *@example.com as a single rule that worked for all mail addressed to the domain. Without this ability, even for only 10 users, that means I have to create 10 mailboxes (as expected), and 20 forwarding aliases (unexpected).
Does anyone else have any advice for these kinds of scenarios? Any hosting companies that are known to support such a setup?
