Hello, We have a voicemail system that emails the voice messages to the users. It uses the Caller ID info in the Display Name area of the From: field.
A problem occurs when the Caller ID contains a comma which causes the recipients email server to see the post with multiple from addresses and some servers (Google's for one) bounce such posts. Instead of a header such as that we now recieve: From: SMITH,JOHN <voicem...@example.com> I've requested the phone techs double quote the Display Name area, ie: From: "SMITH,JOHN" <voicem...@example.com> ... but so far they haven't been able to accomplish this. Turning off use of the Caller ID is one resolution but a non-starter as far as management is concerned, it's quite useful. Can this somehow be worked around in Postfix, automatically double-quoting the Display Name area of the From: field? Thank you, Chris
