We have around 50 domains that aren't core/key business but ideally we want to be able to have the MX records pointing to someone to accept mail for the following:
abuse@ and postmaster@ for all the domains.
various forwarding aliases i.e. sales@ goes to someone@ourcompany dot com
on three or four of the domains we want to have a handful of pop3 mailboxes
smtp relay would be good for the pop3 users
Any suggestions would be appreciated, our registrar doesn't offer this (well they do, but at prices more suited to primary business domains).
I know I could do it in-house with hmail or mailenable but if there is a cheap and reliable way that just takes the hassle away...
