[Xymon] configurable sender email address for alerts?

[Jeremy Laidman]

Some versions of mailx do not support "-r".  However, some versions of
mailx allow you to specify arguments to be sent to sendmail like so:

echo test message | mailx -v -s subject email.address at example.com -
fnoreply at example.com

So in this example, mailx will finish parsing switches when it gets to
addresses, and any switch-like arguments after the addresses will get sent
to sendmail.

Unfortunately, you can't use this with MAILC, as Xymon appends the email
addresses to the end.  Instead, you could create your own script to use in
MAILC.  Something like:

#!/bin/sh
if [ "$FROMADDR" ]; then mailx "$@" -f"$FROMADDR"; else mailx "$@"; fi

Then set

MAILC="FROMADDR='noreply at example.com' mymailx"

Or perhaps install a new MUA, such as "nail" - one that supports "-r".
