Stephan Sachse	ce4a52c22c	sendmail: correct option to set envelope-sender (#3044 ) mailer doesn't set the correct options while calling sendmail. if ``mailer.FROM`` is set to ``"Gitea Webservice" <user@example.com>`` sendmail is called like this ``` Sending with: sendmail [-F user@example.com -i alice@example.com] ``` and doesn't set the envelope-sender. the option ``-F string`` set the sender full name and is used only with messages that has no ``From`` message header. set the envelope sender address with ``-f sender`` (lowercase ``f``) works for me (fedora 27, x86_64, postfix-3.2.4, go1.9.1, gitea-1.3.0)	2017-12-02 11:06:49 +08:00
