[Help] Unable to setup custom SMTP server in TOS 5.1
Posted: 23 Aug 2025, 05:58
I am trying to setup a custom SMTP server via SMTP2go. When entering the username no matter what I use it shows as red and never lets me apply and save the settings.
I'm using TOS 5.1.73 on a TNAS-412D
This is what I get, the error is the same as using the actual username setup in SMTP2go. It seems to do this for any combination of letters, numbers, symbols etc.

Is this a bug or am I missing something?
