Description

While Mail_Hold_Days defines how long temporarily undeliverable mails are held in mail.box, MailServerCutoffDays defines the final upper limit: when mails exceed this age, the router marks them as definitively undeliverable (Dead Mail) or, depending on further configuration, removes them from mail.box. The value prevents mail.box from quietly growing by accumulating “forgotten” old, never-deliverable messages.

Example configuration

MailServerCutoffDays=10

Notes & pitfalls

  • The value should significantly exceed Mail_Hold_Days, otherwise hold mails are discarded too early.
  • Takes effect after a router restart (tell router quit / load router).
  • Pairs with monitoring for Dead Mail (e.g. via the mail.box view or Domino health tools).
  • For compliance workflows, couple with MailJournalling so that discarded mails are still logged in an audit-proof way.
