Hi,
Our server is running Exim 3.33 and consists of around seventy accounts.
Until now we've used the convention of "first name plus surname initial" for
our email address local parts. However, with the growth of the company and
so forth we've had to look at this convention again. We would like to move
towards using "first name.surname". The problem is that I don't really
relish the thought of visiting every PC in the company to change the
settings on the email clients.
I'm wondering if it's possible to rewrite outgoing emails with the new
format. Can someone suggest a way to make Exim take the existing format
local part (eg. bobm) and pick up the actual name from either a list (eg.
bob.monkhouse) and then rewrite the outgoing message to contain the new
format local part?
Any ideas appreciated :-)
