Hello!
I really like the idea of choosing different FROM-adresses when creating
a new mail.
BUT: RoundCube uses just one SMTP-server to send these mails, so there
are several problems:
-the SMTP-server may not allow to send mail from a foreign FROM-address
-several spam-filters will delete mail which was not send through the original
SMTP-server (e.g. a mail with FROM-address "johnny@compuserve.de" will
be deleted if it has not been sent through the Compuserve-SMTP-server)
So please allow to set up multiple SMTP-accounts!
