Authentication failed Code 250

[rob_utopano]

Hello everybody,

i have a big problem.
When i want to send an email over roundcube. I become the failure code 250 and Authentication failed as a message.
I search an error in the configuration of postfix or dovecot, but my search was unsuccessful.

Has anybody the same problem or the solution of this problem ?

Sorry for my bad english, i am german 

best regards,
rob

Hi I have the same problem 
I try to change some setting on the configuration file but no result, the SMTP is Postfix and it works from remote clients.
I have Postfix and enginx on the same server, if i telnet on the smtp ports all seem to be OK.
If I use TLS I get 220 error

Thanks for any help
