If you use the Gmail approach to PassCmd

Change <EMAIL_HERE> to your actual Gmail username.

Save your Gmail password at ~/.emacs.d/mu4e/.mbsyncpass-<EMAIL_HERE>

Encrypt it with

gpg2 -c ./.mbsyncpass-<EMAIL_HERE>

Delete the original plain password file for obvious security reasons.

If you use the Posteo approach to PassCmd

Just set it in .authinfo or .authinfo.gpg (encrypted)

Set SSLVersions depending on the output of

openssl s_client -connect imap.gmail.com:993 -showcerts | grep Protocol

hi, I use mbsync -a and have this error. (only INBOX sync success)

Error: channel gmail-sent: both far side [Gmail]/Sent Mail and near side Sent Mail cannot be opened.

do you have any advice?

thx
