Expire old mails from mailboxes

mail-expire is a small utility which only purpose is to help on keeping the size of multiple mail folders as small as needed (by removing outdated messages). Maildir and Mailbox formats are supported for input, both types are mentioned interchangeably in this manual page. Output goes to Mailbox files. The old messages are compressed with gzip or xz and stored in the file with the name following the pattern MBOXNAME.MONTH_YEAR.gz (or similar). The reference time for the output filename is calculated from the current time minus number of days specified in the first parameter.
