I have not received any SMTP emails from my three NAS today. I use the built-in SMTP. All three were fine last night, no changes made on my end.
Test emails show message sent. The Gmail account that I receive the emails is working as well. Other emails are coming in.
All three are on TOS 7 beta 364

Re: [Help] Emails from NAS stopped working
I just set up a new TNAS F2-425 Plus today, and I am experiencing the same issue. Unable to send emails from the default smtp server. I thought it was a configuration problem on my side, but looking into it, it seems the SMTP service from TerraMaster is shaky at best.

Hello! Thank you for your feedback. The email sending service has now been restored to normal. Please try sending your email again. We sincerely apologize for any inconvenience this may have caused you.

Email stopped again, here in EST time zone. Some sort of maintenance being done in whatever time zone that service is running in?

We will continue to monitor this situation.
If you wish to use the SMTP service more stably, you might consider using the SMTP server of a more mainstream email service in your country or region.

Re: [Help] Emails from NAS stopped working
Thanks, I've used one back a year or so ago when the built in just wouldn't work. Maybe on one of the three I have, I'll switch the SMTP setting.
