Dear Forum,

I use isync/mbsync for my external e-mail provider with imaps.

.mbsyncrc


IMAPAccount foo@bar.de
Host bar.de
Port 993
User foo@bar.de
PassCmd "gpg -q --for-your-eyes-only --no-tty -d ~/.config/mutt/passwd/passwdfile
TLSType  IMAPS
CertificateFile /etc/ssl/certs/ca-certificates.crt


Start mbsync

~$ mbsync -aVVVV
Reading configuration file .mbsyncrc
Channel foo@bar.de                                 
Opening far side store foo@bar.de
Resolving foo..
Opening near side store foo
Connecting to foo.de ([2xxx:xxx:yyyy::333:333]:993)...
Connection is now encrypted                                   
Logging in...
NOT using available SASL mechanism(s): EXTERNAL
Opening far side box INBOX...


Related to "NOT using available SASL mechanism(s): EXTERNAL" I'm not sure if the encryption is ok while login
A Debian system with the same .mbsyncrc do not show this log text.

What do you think?

Thank you!

Hello Forum,

I checked the login process with wireshark and everything seems to be ok.
My provider tells, that every connection must be encrypted.
