Hello and thank you for the reply.
Yes you are correct, this does work which is great news!
I'd like to expand on this by identifying which secretary sent the email. If they both use the same account to login with, they would both then use the same signature. Is there a way for each of the secretaries to have a unique Roundcube login id that uses the same hmailserver mailbox. In this way each secretary can have their own signature.
Roundcube is such a great webmail program...hopefully there is a plugin or config change I can do to satisify the above requirement.
Thank you.
