Roundcube SMTP 451 temporary lookup failure
Roundcube SMTP 451 temporary lookup failure
Hello guys, i have fresh install of sentora.
I configured all settings as on my old server. But when i login to roundcube and try to send email, the windows is saying Error SMTP (451): Cant add recepient "" (4.3.0 <>: Temporary lookup failure)

I dont know where is problem. Passwords to mysql is OK, connection to SMTP server looks ok....

I tried to connect to SMPT server via putty (telnet 25) and when i want manualy send email via console, the server is saying some error.

I think probably DNS? Routes? What do you think?
Thanks given by:
