smtp not working with eM Client

Mail
1

Some of our customers are using eM Client as thier mail client, but it keep giving an error.
So we tried it ourselves and the SMTP keep giving an error.

I tested different settings with ports (25,465 , 587)
Different settings with SSL , TLS and forced but always getting error that verification failed.

Pop3 works without a problem. Mail like outlook , Win 10 Mail , thunderbird work without a problem
Telnet with verification works also.
Just eM Client gives an error.

Getting error 5.7.8 Error: authentication failed: authentication.
This is with SSL disabled. Port 25

Cannot connect error when i have SSL special port. Port 587

Getting error 5.7.8 Error: authentication failed: authentication.
This is with SSL on. Port 465

As said is the mail get recieved. Did it with different accounts. So i think there is a problem with the way it communicates with the server.
Probably the first handshake (helo domain)

So i hope this can get fixed.

Running eM Client 7.1.30794.0

Hello,

Could you please send me the logs to [email protected] in a .txt file so I can take a deeper look into this issue? You will find them in Menu > Tools > Operations. Attach the error screenshot as well.

Thank you.
