--- Comment #1 from Jan-Matthias Braun <jan_br...@gmx.net> --- Further tests with another account revealed, that sending via the EWS resource works. So does sending via a local mail dispatcher, like ssmtp or nullmailer. Although akonadi/kmail2 seems to run into problems with sendmail compatibility issues of those. -- You are receiving this mail because: You are the assignee for the bug.
