Hi,
After migrating from NS7 I have setup 3 different rules in relay tab on the mail app.
If only one rule is active it works, but if I enable more then one, it doesn’t work.
All 3 rules as set up by sender.
In the Queue the error is:
" Delay reason SASL authentication failed; server xxxxxxxx[server IP] said: 535 5.7.8 Error: authentication failed: authentication failure"
What I’m I doing wrong?
