Due to a previous name change, todhunter.com is an alias of
cruzaninc.com so all email addressed to me at either
[EMAIL PROTECTED] or [EMAIL PROTECTED] goes to the
cruzaninc.com address.
Our email domain will be changing to floridadistillers.com and our
email format will be changing to firstname.lastname.
So, my new address will be [EMAIL PROTECTED]
============
IMGate has a sender and/or recipient re-write function, where it can
re-write recipients, or senders, or both.
The file format is self-evident,
#original #re-written
[EMAIL PROTECTED] [EMAIL PROTECTED]
[EMAIL PROTECTED] [EMAIL PROTECTED]
With IMGate as the MX,
1. you could convert all incoming mail for any recipient of the 2 old
domains to [EMAIL PROTECTED]
2. Any Imail user sending out as @todhunter.com or @cruzaninc.com
would actually be delivered to Internet as [EMAIL PROTECTED]
The DNS is dead simple, where mx1.floridadistillers.com is the
IMGate machine, which also serves as the Imail outbound gateway.:
floridadistillers.com. mx 5 mx1.floridadistillers.com.
todhunter.com. mx 5 mx1.floridadistillers.com.
cruzaninc.com. mx 5 mx1.floridadistillers.com.
This approach totally de-couples the public (seen by Internet) switch
over of the 2 old domains to the new domains from your hassles on
Imail and on your users mail clients of converting/folding the old
domains and mailboxes into the new domain. ie, no disruption whatsoever.
I've done this for a couple clients and the switch over was painless
all around, no lost mail, and the switch over (as seen by Internet)
was immediate. No need for 3 months to switch over.
You can leave the re-write function in place forever, so that any
senders on Internet that straggle in switching to the new address
format or who send only very intermittently and keep sending to the
old domains will never have their mail rejected. This really welcome
because users who are subscribed to various e-commerce sites or
send-only list servers under the old domains can stay subscribed
under the old domains while being under no pressure or deadline to go
unsub as old domain and re-sub as new domain.
And of course you get all the other advantages of IMgate. :)
