Description

Domino can encrypt incoming and stored Notes mails using the recipient's public key (Notes / IBM mail encryption). In certain special situations – such as a migration to a different mail server, converting to other formats, or a forensic / diagnostic analysis – this encryption must be omitted temporarily. MailEncryptDisable=1 disables it for the affected server without changing the configuration of the recipient Person documents.

Example configuration

MailEncryptDisable=1

Notes & pitfalls

  • Security / compliance relevant: use only temporarily and with an explicit change ticket.
  • Takes effect after a router restart (tell router quit / load router).
  • Mails already stored encrypted remain encrypted – this only affects new processing.
  • Be sure to disable again after migration (MailEncryptDisable=0 or remove the entry).
