Autoresponder LotusScript

Below is code to create an automated response whenever someone sends a message to a now obsolete mail file.

It can also be used for a “live” mailbox to indicate something like “We’ve received your message and will respond in 24 hours.”

The only requirements are that the Person document (or mail-in document) must still be present in the directory and a valid name is used in the “Run on Behalf of” field of the agent properties.

Usually this is done for someone who is no longer with the company and so is already in the “Deny Access” groups so using the mailfile owner’s name is often not an option.

It is set up to respond to EVERY message sent to it (unlike the Out of Office Agent) to assure the sender that there message HAS been received.

This particular variation was developed after someone with an autoresponder sent a message to one of our autoresponder  mailboxes and ended up with an endless loop. Messages with identical sender and subject will receive only 1 response per day.

Make sure you customize everything in the agent below that has been bolded.

‘This autoresponder will protect against responses from *other* autoresponders by
‘checking to see if we’ve already received a message from them with the same subject already that day.
‘see the “IsMessageUnique” logic for details
‘Also checks for $AssistMail field which indicates that the message was sent by some
‘automated process. This comes from the case where someone sent a message FROM
‘this inbox TO this inbox and started an endless loop.
‘Note also that there is a name in the “Run on Behalf of” field on the security tab.
‘If this field is populated it *must* be represented in the ACL (At least Reader, probably author is safer) or you
‘will get weird errors when the agent runs.
