feed2imap-cleaner deletes old items from IMAP folders specified in the configuration file. The actual
query string used to determine whether an item is old is : "SEEN NOT FLAGGED BEFORE (3 days ago)". Which
means that an item WON'T be deleted if it satisfies one of the following conditions :
• It isn't 3 days old ;
• It hasn't been read yet ;
• It is flagged (marked as Important, for example).
-d, --dry-run
Don't remove anything, but show what would be removed if run without this option.
-f, --configfile
Use another config file (~/.feed2imaprc is the default).
