| Should sendmail run every 15 minutes to process the mail queue, processing and sending out e-mail? If this machine does not run sendmail in daemon mode, you may want to do this to make your outbound mail more reliable.
In most cases, mail queue processing is not required since most mailer programs activate sendmail to process their particular message. A message usually only gets written to the queue (and thus needs a cron entry) if sendmail has trouble delivering it. Example: the receiving mail server is down.
NOTE: Sendmail will not accept inbound connections while processing the mail queue.
NOTE: The 15 minute interval can be easily changed later, see crontab(1). |
