I found IMAP: offlineimap is a syntax violation in my .muttrc file. I am trying to set up offlineimap to sync my gmail account though I already have mutt able to read and write my gmail though not with encryption yet. I have nmh installed and ran install-mh in my user directory. Eventually if I can get offlineimap working I'd like to get whichever version of notmuch will work best with this arrangement installed and working too.
I tried this with different instructions and got as far as offlineimap -o and ran into an error since the gmail-repository ca-cert.crt file couldn't be found on my system.
