Hi everyone, I'm new to this ML.
I have some issue with GMail import settings...
I run a dovecot server (2.3.4.1) on Debian10 and I try to connect to my
accounts from GMail.
It's work fine from thunderbird in pop3,pop3s, imap, imaps... Submission
work too...
But it won't work on GMail except if I set ssl=yes and
disable_plaintext_auth = no...
Then GMail connect without SSL or TLS... And in plaintext.... Very
unsecure...
I can send mail with submission from GMail and ssl=require, that's ok.
If I try to connect with SSL activated I've got : pop3-login:
Disconnected: Too many bad commands
And If I try to connect on port 995 with SSL GMail say that I have some
SSL error, and the log says :

pop3-login: Debug: SSL: where=0x2002, ret=1: SSL negotiation finished

pop3-login: Debug: SSL error: Connection closed
But as I say, all is working fine from Thunderbird...
For the SSL problem this is maybe because GMail doesn't like this
configuration in debian for openssl ?
[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=2
Maybe should I try to set
MinProtocol = None
CipherString = DEFAULT
But this make a lot of security change on my opinion...
Do someone have any tips or suggestion about my problem ?
Thx
Yannick
