Disable Sendmail

Disable sendmail mail receiving, let Lyris receive all mail on your machine.

This is the simplest solution to Lyris/sendmail coexistence. It means that you will no longer be able to receive email directly to your machine. You will, however, be able to use sendmail to send outgoing mail.

If you do not use sendmail to receive mail on your machine, perhaps because you use a mail hub for incoming mail, then this method is the best solution for you.

The advantage of this method is that it is extremely simple and reliable.

The disadvantage is that most sites need sendmail email receiving, and so cannot use this technique.

By default, sendmail is started on Solaris systems by the script file /etc/rc2.d/S88sendmail - if you like, you can modify this file to keep sendmail from being run.

However, a simpler method for disabling sendmail is to assign sendmail SMTP receiving to an unused port, such as port 26, so that it no longer listens on port 25 that Lyris can then listen to.

To move sendmail to another port, such as port 26, add this line to your /etc/mail/ file:


This option is explained in "Options" chapter of the O'Reilly sendmail book.

Once sendmail has been moved off of port 25, Lyris can listen on that port and receive mail on your machine. You can proceed with installing Lyris without worrying about configuring Lyris in any special way.
