No email alert for networker backup jobs

Just verify your notifications and/or use NetWorker's smtpmail program to sent a test mail.

just realized that it is being blocked as i saw the mail logs on our smtp server.

"54+5.7.1+This+message+has+been+blocked+because+the+return+email+domain+is+invalid."

how do i changed the sender email?

currently its SYSTEM@netwrksvr.domain.local

Simply use the 'online help':

E:\nsr\bin>smtpmail -?
Usage: smtpmail [-s subject] [-h smtphost] [-p port] [-f sender] recipient [recipient[...]]
E:\nsr\bin>

So '-t' should do the job.

the test mail works when i changed to < Private Email id removed. TOS76>which is the same as my email domain.

how do i email the sender email that is sending out from the networker program ?

You must change all NW Notifications which send an e-mail appropriately:

what about those notification emails send out upon job completion ?

eg smtpmail -s "Subject" -h mailserver  myemailaddress  since most of the time it is using the server hostname as the sender mail address which is being blocked 

Sorry my friend, but only YOU know YOUR environment.

If there are additional emails triggered by scripts etc. you better change these commands as well.

THINK.

managed to get some help from support. they provided a KB article to change the sending email address using this [-f sender]
