It's on the target list for 2.4 alright. As to a timeframe however - I wish I could be specific there. I've got my hands full at the moment rewriting the server core and sql layers: event-driven, threaded database connection pools, prepared statements, etc. Most of the work has been done already. What remains is making more imap commands non-blocking (by delegating them to worker threads), but a nice pattern is already emerging that can be expanded to the rest of the codebase. But since the native sql layer has been replaced by libzdb, any bugs in libzdb that are exposed by dbmail will have to be fixed by the libzdb people. They have been very good at that, so I'm not worried. But it also means I have to wait with releasing 2.3.3 (the first release with libevent, libzdb and threading) until all supported backends pass the tests. At this moment only the postgres driver is bug-free, but the bugs remaining in the mysql and sqlite drivers are very minor. Once the server-core stabilizes we will have a much better architecture for dealing with scalability issues. That will also free my hands to deal with the other main todos for 2.4: - native SSL/TLS support (John Guthrie has done the groundwork there already) - IMAP THREAD=REFERENCES - selected IMAP extensions (CONDSTORE, LITERAL+, MULTIAPPEND, UIDPLUS) - archive mode (this is what you want) Since I'm doing this on my own, don't expect a final 2.4 release before october, unless a sponsorship deal comes along... -- ________________________________________________________________ Paul Stevens paul at nfg.nl NET FACILITIES GROUP GPG/PGP: 1024D/11F8CD31 The Netherlands________________________________http://www.nfg.nl _______________________________________________ DBmail mailing list DBmail@dbmail.org https://mailman.fastxs.nl/mailman/listinfo/dbmail
