fix: clear attachments and headers in the email cleanup job#443ntwcklng wants to merge 3 commits into
Conversation
The retention cleanup job only nulls text and html, but attachments (base64-encoded, typically the largest column) and headers survive it. Successful sends already clear both right after sending, so this mainly affects failed, cancelled and stuck emails, which keep their attachments forever even with EMAIL_CLEANUP_DAYS configured. Include both columns in the cleanup update and extend the filter so already-clean rows are still skipped.

The setting existed in the env schema but was not mentioned in the self-hosting docs or the example env file.

Reject malformed retention values before enabling cleanup.
apps/web/src/env.js parses EMAIL_CLEANUP_DAYS with parseInt, so EMAIL_CLEANUP_DAYS=30days becomes 30. isEmailCleanupEnabled() then enables the destructive cleanup job, although this comment says non-numeric values disable cleanup. Validate the complete value as a positive integer before parsing, or change the documented contract. A configuration typo must not silently activate data deletion.

Clears values, does not delete columns. Drop the claim about non-numeric values, since the setting is parsed leniently.

Problem
The retention cleanup job (
cleanup-email-bodies.ts, enabled viaEMAIL_CLEANUP_DAYS) nullstextandhtmlon old emails but leavesattachmentsandheadersuntouched. Attachments are stored base64-encoded and are typically the largest column on the row.Successful sends already clear both columns right after sending (
email-queue-service.ts), so delivered mail is fine. But emails that never complete the send keep their attachments forever, even with cleanup enabled:latestStatus: "FAILED"QUEUED(see 🐞 - Emails stay stuck in "Queued" forever when a sending limit is exceeded #407 / 🐞 - Callback Success, but all emails appear as 'Queued' #406)For self-hosters the cleanup job exists precisely to bound DB growth, and these rows are the heaviest ones it currently skips.
Fix
Include
attachmentsandheadersin the cleanupupdateMany, and extend theORfilter with both columns so already-clean rows are still excluded from the daily run.Note on behavior: after cleanup, a failed email's attachments are no longer available. That matches the job's existing contract —
text/htmlare already discarded the same way once a row passes the retention cutoff.Docs
EMAIL_CLEANUP_DAYSexisted in the env schema but wasn't documented anywhere, so this also adds it to the self-hosting overview (as an optional step) and to.env.selfhost.example.Verification
pnpm test:unitpasses (20 files, 120 tests). The job change is limited to the where/data shape of the existing query; the diff follows the file's current formatting.Summary by CodeRabbit
