Issue Webmail don't send email

[CercamiFacile]

Hi, I've 4 server with plesk 18.0.31 #2 and from all server no client can send mail from webail and horde or roundcube. They have always the same error: "There was an error sending the message: Server denied authentication"

From pc all work fine but with webmail is impossible to send email. This is a problem that has always been on emails, but I would like to solve it once and for all.
Thanks

Is there port 465 is open and can you connect to this port? Check it with

# lsof -i tcp:465

and

# telnet localhost 465

-bash: telnet: command not found

Please install it and repeat command. If you have Centos:

# yum install telnet

For Debian or Ubuntu:

# apt install telnet

[root@ns3112772 ~]# telnet localhost 465
Trying ::1...
Connected to localhost.
