Description

If the router cannot deliver a message directly (for example, when the recipient server is temporarily unreachable), it remains in mail.box or the hold queue. Mail_Hold_Days defines how long the router keeps the mail in that state. After the period elapses, the mail moves to mail.box as Dead Mail (status “Dead”) or is deleted – depending on the router configuration. The default is 5 days.

Example configuration

Mail_Hold_Days=3

Notes & pitfalls

  • Very long hold times lead to a growing mail.box and more router load.
  • Takes effect after a router restart (tell router quit / load router) or the next configuration reload.
  • Pairs with MailHoldUndeliverableOnly and the router settings in the Configuration document.
  • For compliance / audit purposes, combine with journaling if needed – the hold queue is not a mail archive.
