There is an old (2008/2009) thread on an identical sounding bug. But that is for an older version of Mutt than I have.
I am using: Mutt 1.5.20 (2009-12-10) I am trying to connect to a Microsoft exchange server and have the following muttrc: set smtp_url=smtp://[email protected] set smtp_authenticators=login set smtp_pass=PASSWD set [email protected] When I use mutt in interactive mode it works fine and sends messages without prompting for authentication. When I use mutt with the -i option: mutt -i ~/blah.txt -s "Test message" [email protected] It works in a semi-interactive mode and there are no errors, but it doesn't send anything. When I use mutt in batch mode: cat ~/blah.txt | mutt -s "Test message" [email protected] or: mutt -s "Test message" [email protected] < ~/blah.txt Then it segfaults.
