Thanks to the hackfest time Igalia gently gives me every week I could resume the work I had previously started to add
ENVELOPE support to tinymail.
What’s this stuff about? Well basically what we can do now is ask the server for
ENVELOPE instead of fetching a random set of headers (like ‘From:’, ‘Subject:’ …). Why is this cool? For several reasons:
- Speed: IMAP servers do cache
ENVELOPEinformation so they do not have to inspect every email message to extract the requested headers. They can give you
ENVELOPEblazingly fast (I run a rough test and downloading a folder with ~1500 headers from AOL IMAP server lasted twice the time of downloading
BODYSTRUCT, and this means minutes).
ENVELOPEis smaller in size than headers as the name of the headers is not transmitted over the network
- Future: RDF storage support in tinymail is now closer
You can find this new feature in trunk.
