Greetings,

I need to modify the "From:" header line in incoming e-mail messages ONLY IF "Message-Id:" starts with a defined string.

The action pattern would be similar to the following:

/^From: (.*)@johndoe.com/ REPLACE From: ${1}@ext.johndoe.com

Can you suggest a way to accomplish this?


TIA, Gabriele
