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 ( xxxx at abc.com) if I need send email to external email such as gmail or SMS service. I had added Xymon XXXX at abc.com 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 alex. at abc.com alexalex at extenalweb.com 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 xymon_site1 at mydomain.com
