REFERENCE
Description: Specifies the number of days after which the server returns undelivered mail to the sender. Increase this setting when you have a lot of mail returned in one day or when you are sending mail to foreign domains.
Note To specify a period of less than one day, use the NOTES.INI setting MailTimeoutMinutes.
Applies to: Servers
Default: None, although if this setting is omitted, undelivered mail is returned after one day.
UI equivalent: None, but you can specify this setting in the NOTES.INI Settings tab of the Configuration Settings document in the Domino Directory.
