I've been trying to set of my new posteo.net email account on emacs/mu4e (I have a gmail account that works on emacs/mu4e but would like to switch). I can successfully receive emails via offlineimap but cannot send emaisl. Specifically, I get the following error message:
smtpmail-send-it: Sending failed: 535 5.7.8 Error: authentication failed: in response to AUTH PLAIN
I have the following variables set in emacs:
smtpmail-stream-type 'starttls
smtpmail-default-smtp-server "posteo.net"
smtpmail-smtp-server "posteo.net"
smtpmail-smtp-service 587)
I tried a few other combinations, i.e., posteo.de, smtp.posteo.net, smtp.posteo.de, as well as using ssl for smtpmail-stream-type (along with port=465), all failing with the same message. Any tips would be welcome!
