Apple Mail not sending EMPTY Emails
I searched like crazy because emails from some accounts got sent from Mac Mail, others didn't . From those that didn't send, they worked from iOS with no problems.
After all I experienced something weird- this seems to be caused, if the email text is empty! From iOS they do have a signature- it works. From Apple Mail some accounts have signatures and work, others don't have ist and won't send. I can reproduce that meanwhile.
I know- one may ask "what sense does an empty mail make" but I sometimes send Mails having a short message just in the subject.
Can someone confirm?
