commands and replies will be printed. Useful to debug TLS
connection and authentication problems.
+--batch-size=<num>::
+ Some email servers (e.g. smtp.163.com) limit the number emails to be
+ sent per session (connection) and this will lead to a faliure when
+ sending many messages. With this option, send-email will disconnect after
+ sending $<num> messages and wait for a few seconds (see --relogin-delay)
+ and reconnect, to work around such a limit. You may want to
+ use some form of credential helper to avoid having to retype
+ your password every time this happens. Defaults to the
+ `sendemail.smtpBatchSize` configuration variable.
+
+--relogin-delay=<int>::
+ Waiting $<int> seconds before reconnecting to SMTP server. Used together
+ with --batch-size option. Defaults to the `sendemail.smtpReloginDelay`
+ configuration variable.
