--- name: "dbmail-util" section: "8" platform: "linux" package: "dbmail" version: "3.5.6-2" release: "Arch Linux 2026-11-01" platforms: ["linux"] url: "https://new.carta.tech/dbmail-util" --- # dbmail-util(8) maintains the integrity and cleanliness of the DBMail datatables. ## NAME dbmail-util - maintains the integrity and cleanliness of the DBMail datatables. ## SYNOPSIS ``` dbmail-util [options] --all-checks dbmail-util [options] --test-integrity dbmail-util [options] --check-body dbmail-util [options] --purge-deleted dbmail-util [options] --set-deleted dbmail-util [options] --clear-replycache time dbmail-util [options] --clear-iplog time dbmail-util [options] --rehash ``` ## DESCRIPTION The dbmail-util program offers a database cleanup and integrity check. All messages set for deletion (status 2) will be marked for final deletion (status 3). All message marked for final deletion will be cleared from the database. The integrity check will check for unconnected mimeparts, headervalues, messages and mailboxes. By default, checks are read-only. Pass the --no option to respond no to any prompts. Pass the --yes option to make read-write changes, responding yes to any prompts. ## OPTIONS - \-b, --check-body Check and rebuild the body/header/envelope cache tables. - \-d, --set-deleted Queue all messages marked with the DELETE (2) status for final purging, by setting the status value to PURGE (3). The status field is set to DELETE by either the IMAP-EXPUNGE or POP3-DELE commands. - \-p, --purge-deleted Remove all messages with a PURGE (3) value on status field. To purge messages currently marked with the DELETE (2) status, run with the -pd options twice. This is not recommended; it is better to leave a grace period for old messages before permanently wiping them from the database. - \-s, --remove-invalid-aliases Remove dangling/invalid aliases and forwards. - \-t, --test-integrity Test for message integrity. - \-a, --all-checks Perform the above checks: --check-body --set-deleted --purge-deleted --remove-invalid-aliases --test-integrity - \-r, --clear-replycache time Clear the reply cache used for autoreplies and Sieve vacations. The time is specified as \h\m (don’t include the angle brackets, though!). - \-l, --clear-iplog time Clear the IP log used for IMAP/POP-before-SMTP. The time is specified as \h\m (don’t include the angle brackets, though!). - \--rehash Rebuild hash keys for stored messages - \--erase days Delete messages older than date in INBOX/Trash - \--move days Move messages from INBOX to INBOX/Trash - \--inbox name Inbox folder to move from, used in conjunction with --move - \--trash name Trash folder to move to, used in conjunction with --move **Common options** - \-n, --no Show the intended repairs without making any changes, i.e. no to all. - \-y, --yes Perform all repair actions , i.e. yes to all. **Maintenance options** - \--rehash Rebuild the hash values for all the message parts in the database. You need to run this after modifying the hash\_algorithm config option. - \-e, --check-empty-cache Check for empty envelope cache. **Migration options** - \-M, --migrate-legacy limit migrate legacy 2.2.x messageblks to mimeparts table. - \-m, --migrate-limit limit limit migration to \[limit\] number of physmessages. Default 10000 per run. ## COMMON OPTIONS - \-f, --config configfile Specify an alternate config file. Use dbmail-\ --help to show the default location. - \-q, --quiet Quietly skip interactive prompts and helpful status messages which would otherwise be printed to stdout. Use two -q’s to silence errors which would otherwise be printed to stderr. - \-v, --verbose Operate verbosely. Some of the utilities in the DBMail suite can take two -v’s for extra verbosity. Those which don’t understand this convention won’t complain about having the extra -v and will simply operate at their normal verbosity. - \-V, --version Show the version and copyright, then exit. - \-h, --help Show a brief summary of options, then exit. ## RETURN VALUES Returns 3 when errors are found but could not be fixed due to failure, 2 when errors are found but *-y* was not provided or *-n* was provided, 1 when errors are found and fixed successfully, 0 when no errors are found. ## EXAMPLES Regular maintenance can be run as a regular cron job: ``` dbmail-util --all --yes --verbose ``` To set all messages with the DELETE status to PURGE status, and permanently remove all messages previously set to PURGE status: ``` dbmail-util --set-deleted --purge-deleted -yes ``` To get a listing of the changes that would be performed for all actions: ``` dbmail-util --all --no ``` To remove all IP log entries more than three days old: ``` dbmail-util --clear-iplog 72h --yes ``` After upgrading from DBMail 2.0 or truncating the cache tables, run this command to populate the cache: ``` dbmail-util --check-body --yes ``` ## SEE ALSO [dbmail(1)](/dbmail/1.md), [dbmail.conf(5)](/dbmail.conf/5.md), [dbmail-deliver(1)](/dbmail-deliver/1.md), [dbmail-export(8)](/dbmail-export/8.md), [dbmail-httpd(8)](/dbmail-httpd/8.md), [dbmail-imapd(8)](/dbmail-imapd/8.md), [dbmail-lmtpd(8)](/dbmail-lmtpd/8.md), [dbmail-pop3d(8)](/dbmail-pop3d/8.md), [dbmail-sieved(8)](/dbmail-sieved/8.md), [dbmail-sievecmd(8)](/dbmail-sievecmd/8.md), [dbmail-users(8)](/dbmail-users/8.md), [dbmail-util(8)](/dbmail-util/8.md) ## BUGS For the latest announcements, please subscribe to the **DBMail announce mailing list**\[1\] For general discussion, please subscribe to the **DBMail general mailing list**\[2\] If you experience an issue with DBMail, please report it on the **DBMail Bug Tracker**\[3\].
