CA Service Desk Manager SMTP email notifications are not working - SDM logs are getting flooded with messages like:
mm/dd hh:mm:ss.xx <server_name> pdm_mail_nxd 5072 ERROR hunny_mail_intf.c 1921 ThrdLogger Sess:45829:1:0 SMTP RCPT command failed Error (450) 4.1.2
<firstname.lastname@example.org>: Recipient address rejected: Domain not found
mm/dd hh:mm:ss.xx <server_name> pdm_mail_nxd 5072 SIGNIFICANT hunny_mail_intf.c 1211 Send Mail retry scheduled
mm = month
dd = day
hh = hour
mm = minute
ss = second
xx = millisecond
<server_name> = name of the server
email@example.com = email
The error normally indicates that the mail server is rejecting the email because of some settings on the SMTP server.
One way to fix this is to:
Login with an Administrator userid.
Go to "Administration" tab.
Select option "mail_smtp_hosts" and provide the correct SMTP host information. Consult your Email server admin for correct values.
Restart Service Desk service.
Do engage your SMTP Admin to ensure correct values are obtained and any other possible issues could be addressed at the same time.
