TwitterHello,
Yesterday I decided to install Plesk web admin in my VPS since I am a client plesk in another dedicated server that I have since 2010, the installation was done successfully and the panel is working very well.
After everything was set up I created an e-mail and everything was working through webmail and it continues, only through the MS Outlook 2013 client the receiving server works but the SMTP gives error (0X800CCC80 - None of this client's authentication methods are supported by the server).
I have seen several similar posts in this forum but none solves my problem, I wonder if somebody knows the solution to this problem.
With SMTP authentication the error 0X800CCC80
Without SMTP Authentication works but I get an error by mail '554 5.7.1 Relay access denied'
If somebody can help.
Server its Postfix with Dovecot.
