Impossible to send emails from Thunderbird from last custombuild updates

[pppplus]

Hi

After automatic updates on directadmin, impossible to send email.
The message in logs is : rejected MAIL <mail here> authentication required

The problem is only on 1 server.
No problem on the 2 others.

Parameters to send are :
SMTP port 587
name of server mail.domainname
security : none
authentification : password only

The 3 servers (should) have the same configuration.


Thanks for you help.

I'm seeing the exact same. You need to roll back your Dovecot version to 2.3.21.1-- I assume that got (auto) updated to the 2.4 version.

Different thing.

 

[Active8]

security : none

That is the issue, you have to edit this and choose TLS

TLS does not work

 

[Active8]

try port 465 SSL or port 587 STARTTLS

EDIT: check your server config if there is any encryption is served :

//email/testTo:

www.checktls.com

EDIT 2: I have checked the domain in your signature and see some issues :

Cert Hostname DOES NOT VERIFY (mail.ecocaps.fr != host1.hb50.fr | DNS:host1.hb50.fr | DNS:server-54-36-122-31.da.direct)

Specially this part : DNS:server-54-36-122-31.da.direct) check your server config

You're right, I just have to add SSL on mail.domainName.

After that, I can use TLS when sending with thunderbird.

THANKS !
