Nagios Support Forum

I am trying to change the return address for Nagios.

When it sends alerts, it has a return address of [email protected]
In Admin/manage email settings, do have it set to be what I want.
If I click "sent a test email", it sends with the proper return address, but when it sents alerts, its wrong.

I need to fix this as I can acknowledge alerts via email

I saw the post http://support.nagios.com/forum/viewtop ... ss#p115017
but I don't have the file " vi /etc/mail/sendmail.mc"


I have tried using sendmail and smtp but no luck

hmmmmmm, I may have fix it....not sure if I did it the right way.

It appears the vmware image I downloaded was setup with postfix, not sendmail

what I did was opened /etc/postfix/main.cf

in the section named "SENDING MAIL"
I added a line that reads then I restarted postfix Had it send a warning, and it appeared correct.

If I should have done it differently, please let me know.

Glad you figured it out.
Here is a link to postfix's site on how to rewrite postfix addresses.

We'll close the ticket for you.
