Hi All,


I had a Xymon server need send email with a special sender email address,
because of mail server had limitation sender must be company email domain (
user-8fda1a1d6b1b@xymon.invalid) if I need send email to external email such as gmail or SMS
service. I had added Xymon user-8fda1a1d6b1b@xymon.invalid in Sendmail genericstable but not
working. Also, I had tried to rename the hostname from
xymonserver.localdomain.com to xymonserver.abc.com it works, but we
cannot change the hostname it will make the other problem.


I can't use -r in Alert.cfg, for example : MAIL -r user-0c97b362772f@xymon.invalid
user-35ab528d2aec@xymon.invalid SERVICE=uptime,conn


it will not send out and Xymon alert.log shows below error


mail: option requires an argument -- r

Usage: mail -eiIUdEFntBDNHRVv~ -T FILE -u USER -h hops -r address -s
SUBJECT -a FILE -q FILE -f FILE -A ACCOUNT -b USERS -c USERS -S OPTION users


so, I tried to change x=xymonserver.cfg but not working, I added -r in
Mail="$MAILC -s"


# For the xymond_alert module

MAILC="mail"                            # Command used to send an e-mail
with no subject

MAIL="$MAILC -r -s"                     # Command used to send an e-mail
with a subject


may I know the setting of xymonserver.cfg to allow MAIL Command to use -r
in Xymon alert.cfg?


P.S: I can use mail -r to send out email in centos 7.

 Xymon 4.3.28

How I did this was just to change Postfix myorigin to the domain of choice
and change the entry in xymonserver.cfg MAILC="mail -r username"

e.g. xymonserver.cfg: MAILC="mail -r xymon_site1"
/etc/postfix/main.cf: myorigin = mydomain.com

This will send emails from user-614793e15de4@xymon.invalid
