I've been using mailutil from the UW-IMAP suite, after seeing some recommendations for it on this list and with my distro. However, as far as I know, it won't automatically operate recursively over your mailboxes (it might: I haven't been looking for that feature). As some other messages I've posted attest, I've been surprised how slowly I can stuff messages into the cyrus server. My guess is the problem is with cyrus, but it might be with mailutil. Parallelizing the copies speeds things up quite a bit, and in my tests I get the best performance with ext3 partitions mounted noatime. I'll post more results when I finish trying out some other filesystems. -- Ross Boylan wk: (415) 514-8146 185 Berry St #5700 ross@xxxxxxxxxxxxxxxx Dept of Epidemiology and Biostatistics fax: (415) 514-8150 University of California, San Francisco San Francisco, CA 94107-1739 hm: (415) 550-1062 ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
