mbox/maildir migration

[Michael Bartlett]

hi all i've been having some incredible performance problems on my box recently. i have been reading around a bit and have come to the conclusion that the high level of access on my machine would be better suited using maildir. i'm getting so many lock errors! at the moment i'm using cucipop, but am quite interested in moving to qpopper. is there anyway that i can configure qpopper to collect mail from both the mbox and maildir locations?   the system manages around 30 000 mails a day - all of which are mission critical and so i'm a little hesitant to do a complete cut-off and switch over in case i lose mails.   if not, can anyone recommend any tools that can migrate mbox mails -> maildir. i am using exim as my MTA. cheers mike
