Hi @kundan,

I have same problem even though I didn’t upgrade OJS. Sending email doesn’t work suddenly.

Hmm. It can’st stop suddenly easily. Please check did your sysadmin changed something on mail server, closed some port or stopped mailserver service on your server.
Did you change any settings for mail in
