I have a test installation with a Mikrotik hAP ac V6.44.
I have added the Usermanager and connected this with the hotspot of the mikrotik.
I have "Signup allowed" enabled and can create a user with a free profile.
The user creation is fine and the user is working, but the mikrotik is trying to send an email and I get the error: invalid body
The e-mail configuration of the mikrotik is fine. I can send test emails.
I use the default text for the e-mail message.
The mikrotik logs says: Error sending e-mail <Account Info>:invalid BODY
thx for your help.
