- I have a similar setup here, with the mailhost being a Sun running
- IDA and a bunch of SGIs and DECs running as mail slaves. The problem
- is that the SGI expects different permissions in the mail spool than
- the Sun. Specifically, on the Sun, the directory is mode 1777 and the
- mailboxes are created 600. The SGI uses a "mail" group and sets group
- write permissions on the spool directory and mailboxes.
-
- If you fix things so that everything including local mail is sent to
- the mailhost, it will fix your delivery problems. But there is one
- other gotcha: When the SGI starts up mail, it tries to "fix" the
- permissions in the spool directory to conform to what it thinks they
- should be. So, on your SGIs that are mounting the mail spool, you
- need to comment out a few lines in /etc/init.d/mail so that it doesn't
- try to do anything to /usr/mail.
-
- I did this and things have been running smoothly for several months
- now.

- If you're running Irix 4.0.5, you already have IDA sendmail. All you
- should have to do is build a cf file from Sendmail.mc in the IDA
- distribution, and define MAILHOST in your M4 file. If you'd rather
- hack on SGI's sendmail.cf, you can replace calls to the "local" mailer
- with appropriate calls to the "ether" mailer. For example,
-
- R@ $#local$:$n
-
- becomes
-
- R@ $#ether$@$F$:$n
-
- Where the F macro is the name of your mail server.
