This idea has been merged into another idea. To comment or vote on this idea, please visit NTS-I-409 Selection of signature independent of mail or reply.
In some organisations one person works for different associations and have to send mail in one case for the email@example.com address, in the other case with firstname.lastname@example.org.
Users have to change location and sender address to send correctly. The domains are all allowed in the domain. It should be more simple to change the signature and with the signature the senders address and internet domain to make work a little bit easier. Excuse my bad Englisch :-)
