Gnus, Dovecot, OfflineIMAP

This is a followup, effectively, to Roland Mas’ article Gnus, Dovecot, OfflineIMAP, search: a HOWTO .

I went thru Roland’s HOWTO, and have a few comments on variances that I noticed:

  1. I first installed OfflineIMAP; this worked pretty much fine as described. I didn’t bother adding the extra Python code for propagating Gnus expiry material, as I generally don’t use it.
  2. I had a couple problems setting up Dovecot:
    1. By default, Dovecot uses Maildir++ folder handling, which isn’t consistent with how OfflineIMAP stores folders.There’s an additional option needed to cope with this:
      mail_location = maildir:~/Maildir:LAYOUT=fs
    2. Perhaps because of the above, I couldn’t readily get Gnus to talk over a pipe to a Dovecot process.Not a big deal – I have Gnus speak to Dovecot via talking to the socket, which is the usual thing one would do with Dovecot anyways.
  3. It seems to me as though Gnus should be able to talk directly to Maildir. It does, after all, have a protocol for it (nnmaildir).I couldn’t struggle my way thru the Gnus documentation to properly set up a virtual server for nnmaildir to do this.

    This would be pretty valuable in that it would eliminate the need for Dovecot altogether. Perhaps it’s a documentation problem that nobody seems to know how to do this.
