| ipurge − delete mail from IMAP mailbox or partition based on age or size | 
| ipurge [ −f ] [ −C
config-file ] [ −x ] [ −X ]
[ −i ] [ −s ] | 
| Ipurge deletes messages from the mailbox(es) specified by mailbox-pattern that are older or larger than specified by the -d, -b, -k or -m options. If no mailbox-pattern is given, ipurge works on all mailboxes. If the -x option is given, the message age and size MUST match exactly those specified by -d, -b, -k or -m. The are no default values, and at least one of -d, -b, -k or -m MUST be specified. Ipurge by default only deletes mail below shared folders, which means that mails in mailbox(es) below INBOX.* and user.* stay untouched. Use the option -f to also delete mail in mailbox(es) below these folders. Ipurge reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C. | 
| −f | Force deletion of mail in all mailboxes. | 
| −C config-file | 
| Read configuration options from config-file. | 
| −d days | 
| Age of message in days. | 
| −X | Use the time the message was inserted into the mail store instead of Date: header for −d matches. | 
| −b bytes | 
| Size of message in bytes. | 
| −k Kbytes | 
| Size of message in Kbytes (2^10 bytes). | 
| −m Mbytes | 
| Size of message in Mbytes (2^20 bytes). | 
| −x | Perform an exact match on age or size (instead of older or larger). | ||
| −i | Invert mach logic: -x means not equal, date is for newer, size is for smaller. | ||
