chewmail - mail archiver
chewmail [OPTIONS] <MAILBOX> ...
chewmail is a program for archiving mail. It is inspired by the by the
Python-based archivemail, but with more useful semantics. All mail is
archived to the mailbox specified with the --output-box switch, in mbox
format. It can read mailboxes in mbox, Maildir and MH formats.
Internally, chewmail uses Mail::Box, so it support file names and URLs
supported by that module.
-o mailbox-format, --output-box=mailbox-format
The mailbox to archive messages to. The mailbox is run through the
Date::Format module, so it supports all it’s conversion specifiers.
The date and time is relative to the messages timestamp, or the
current time if the timestamp is impossible to determine. A sample
of the conversion specifiers follows:
%b month abbr
%d numeric day of the month, with leading zeros (eg 01..31)
%e numeric day of the month, without leading zeros (eg 1..31)
%G GPS week number (weeks since January 6, 1980)
%h month abbr
%H hour, 24 hour clock, leading 0’s)
%I hour, 12 hour clock, leading 0’s)
%j day of the year
%l hour, 12 hour clock
%L month number, starting with 1
%m month number, starting with 01
%o ornate day of month -- "1st", "2nd", "25th", etc.
