I will try and keep this as simple as possible.
We have a company that are changing there name and along with that they are changing there email addresses.
At the moment they have say three pop3 email addresses firstname.lastname@example.org, email@example.com and firstname.lastname@example.org which are collected by a pop3 connector and distributed to each individual mailbox.
The SMTP connector is setup to send out through a smarthost mail.domain.com and authenticated with one of the email addresses.
The new email addresses will be email@example.com, firstname.lastname@example.org and email@example.com
The problem is as follows - each user will want to send and receive from both accounts.
For example - user 123 will need to receive all mail from firstname.lastname@example.org and all mails from email@example.com and also be able to send from both address too.
Do i need to set up a second SMTP connector to allow the users to send through, 1 connector with mail.domain.com and the second one with mail.newdomain.com set up.
I hope that makes some sense to you and hopefully you can help
