There is a bug open to merge the offline IMAP support, which can be tracked under #11832. However, there's not a bug to track "the IMAP IDLE stuff". Have you got a link to the patches? EDIT: More info here: http://blogs.igalia.com/svillar/2010.../#comment-3162 and https://bugs.maemo.org/3888 Short version: seems that some work would need to be done to prevent IMAP IDLE being an enormous power drain. If a developer wanted to pick up on it and make the PR_Poll() changes discussed, then it'd be includable in the CSSU, IMHO
