It looks that there could be a couple of aspects to this problem: Firstly, perhaps the default value of mail.server.default.mime_parts_on_demand should be set to True, rather than False, when Thunderbird is first installed.
Secondly, it appears then when for whatever reason parts are pre-loaded, they should be cached somehow, so that they don't need to be downloaded a second time. Finally, it's not clear what part the Bayesian spam filter is playing in all this: according to the Mozilla bug report, it looks as thought perhaps sometimes the spam filter wants to download the entire message so that it can run its algorithm on the message+attachments. -- mozilla attachments are dowloaded multiple times https://bugs.launchpad.net/bugs/275471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
