I am using "whatever Debian came with!" :-) I believe it is mbox: the files are /var/mail/[username] I am a little surprised to hear multiple connections to the same mailbox is unsupported. I have had plenty of this over the years (most in the form of Outlook or Mac Mail on a desktop and blackberry or other phone at the same time) and it has been working fine. The only issue we've run into is users employing POP on their desktop at the same time as IMAP on their phone. That causes the same kind of corruption. We have discouraged this and suggested they switch to using IMAP in both places. This issue with the iPhones appeared here in the last 6 months when we upgraded this box - moving away from a custom UW-imap build in favor of the package maintainers version. I suppose I could go back to building it myself - it was just a hassle to figure out how to get c-client to install correctly. _______________________________________________ Imap-uw mailing list [email protected] http://mailman2.u.washington.edu/mailman/listinfo/imap-uw
