I think this is more of a message-mode question than a notmuch question. I use something very similar to code attached below, which is rather brute-force, but does the job for me. --- Keith ----- (defun kea/send-mail-with-x () (interactive) (setq smtpmail-smtp-server "smtp.x.com" smtpmail-smtp-service 587 smtpmail-local-domain "x.com" smtpmail-auth-user nil smtpmail-stream-type 'starttls)) (defun kea/send-mail-with-y () (interactive) (setq smtpmail-smtp-server "email.y.com" smtpmail-smtp-service 587 smtpmail-local-domain "y.com" smtpmail-auth-user nil smtpmail-stream-type 'starttls)) (defun kea/message-select-mail-dest () (cond ((string-match "<kea@x.com>" (message-field-value "From")) (kea/send-mail-with-x)) (t (kea/send-mail-with-y)))) (kea/send-mail-with-y) (add-hook 'message-send-hook 'kea/message-select-mail-dest)
