Here's something I would like to see in a future version. Posting to the list to curb the inflation of online accounts.
Right now, there are two query_command configuration variables, mime_type_query_command and query_command. The second one should really be renamed address_query_command to describe its purpose more clearly. This of course would be a breaking change, so I'm not feeling too strongly about it. Maybe a 3.0 item. The context is that at some point there might be further query options. One option I would absolutely love to see included is a query for S/MIME certificates, similar to query_command for address lookup. It would search a directory for S/MIME certificates for all recipients where no cert is available in the local keybox, and present them for selection with an accept once/permanently choice (discard after, or import into user keybox with gpgme API or gpgsm --import). I have a script that does this, but no mutt integration. Looking at recent list postings, it seems that I'm probably not the only one who thinks S/MIME support could do with some improvements :)
