mbox
For mbox, the mail separator is "From " in the beginning of lines. The incm utility does not convert ">From " to "From " in the beginning of lines in the body. On Solaris, Content-Length: should be used with the -c option to tell the end of mail.To lock mbox, a lock file("<user>.lock"), flock() or lockf(), and open(O_EXLOCK) are used.
maildir
For maildir, no lock and no separator are necessary.Consider the following situation:
cur/{1,2} new/{3,4}
Executing incm without the options results in:
cur/{1,2} new/{} to inbox: {3,4}
Executing incm with the -a option results in:
cur/{} new/{} to inbox: {1,2,3,4}
Executing incm with the -b option results in:
cur/{1,2,3,4} new/{} to inbox: {3,4}
Executing incm with the -a option and the -b option results in:
cur/{1,2,3,4} new/{} to inbox: {1,2,3,4}So, if both options are specified, messages are retrieved multiple times.
