Hi, I'm currently working on an app that needs to read mails from an Kmail mail folder. I've downloaded some RFCs from sunsite.auc.dk. My problem is that I got lost somehow in the hundreds of files there. I found the RFCs that describe the mail format, but I couldn't find anything about the storage of mails. Is the way Kmail stores mails (mbox ?) a defined standard? Especially, are there any naming conventions for the files in which mails are stored or for the (hidden) .index files? (I think about reading mails stored by other email clients). Could someone please explain that or point me to the right document? Thanks a lot, Michael
