+.SS Selection based on sender address:  sendfrom
+One or more
+.I sendfrom
+profile components can be used to select a mail server address, mail server
+port, or any other switch that can be supplied to
+.BR post .
+It works by first looking at the sender address and domain name in the
+message draft, as described below.
+It then looks for a corresponding profile entry, which contains the
+.B post
+switches.
+To enable, add profile entries of the form:
+.PP
+.RS 5
+.RI sendfrom- "address/domain name" : " post switches"
+.RE
+.PP
+The email address is extracted from the Envelope-From:  header, if not blank,
+the Sender: header, or the From: header line in the message draft.
+Multiple profile entries, with different email addresses or domain names, are
+supported.
+This allows different switches to
+.BR post ,
+such as -user, to be associated with different email addresses.
+If a domain name is used, it matches all users in that domain.
+.PP
+Here is an example profile entry using OAuth for an account hosted by gmail:
+.PP
+.nf
+.RS 5
+sendfrom-gmail_address@example.com: -saslmech xoauth2
+.RS 5
+-authservice gmail -tls -server smtp.gmail.com
+-user gmail_login@example.com
+.RE
+.RE
+.fi
+.PP
+(Indentation indicates a continued line, as supported in MH profiles.)
+The username need not be the same as the sender address, which was extracted
+from the appropriate header line as noted above.
