Hi, back on May 1st I ran ten nprinting jobs. All ran without errors and all had an email to send to requestors and all had successfully sent emails on previous iterations. On May 1st, the first five emails came through but the last five did not. No emails have come through since and our support department has confirmed they are not being quarantined or anything. (In the past the issue was related to a security change that caused the emails to get intercepted and someone had to put them back on a white list.) The environment is a dedicated windows/nprinting server environment without outlook or office etctera on it. I think it might need someone to right-click restart the smtpsvc service, but I'd expect a stopped service to throw an error message, so it might be an issue on another point between this server and the company's main email firewall something.
Any idea where I should look for what allows all the jobs to run without errors, let the first five emails through on a given day, and no emails for a couple of weeks since then? Any help is welcome, thanks!
Note: I'm not the server admin technically, but the guy who configured all the nprinting server/email stuff left a few months ago and new admin is learning his way around various servers now.
