An answer from Peter:

The 6 first characters in the file name are generated by using the UNIX time stamp (=seconds since Jan 1, 1970) using the following characters: "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
The 7:th charachter is picked from this list: "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
It is usually always the first character ('0'). However, if that file for some reason exists, the next N:th character in the list is used until PMMail can get a filename that is unique. This will for instance happen whenever PMMail creates more than 1 
file/second. As you can see, PMMail has a builtin limit of 62/files per second. If PMMail downloads messages faster than this, it will no longer work correctly ;-)

Thanks,
Peter
