Notes on the Sieve implementation for Exim
the UTF-8 reason is processed to compose the resulting message.
-Envelope Sender
-
-The vacation draft does not specify the envelope sender. This
-implementation uses the empty envelope sender to prevent mail loops.
-
-
Default Subject
The draft specifies that the default message subject is "Re: "
Rate Limiting Responses
-The draft says:
-
- Vacation responses are not just per address, but are per address
- per vacation command.
-
-This is badly worded, because commands are not enumerated. It meant
-to say:
-
- Vacation responses are not just per address, but are per address
- per reason string and per specified subject and ":mime" option.
-
-Existing implementations work that way and it makes more sense, too.
-Including the ":mime" option is mostly for correctness, as the reason
-strings with and without this option are rarely equal.
-
-This implementation hashes the reason, specified subject and ":mime"
-option and uses the hex string representation as filename within the
-"sieve_vacation_directory" to store the recipient addresses for this
-vacation parameter set.
+This implementation hashes the reason, specified subject, ":mime"
+option and ":addresses" option and uses the hex string representation
+as filename within the "sieve_vacation_directory" to store the recipient
+addresses for this vacation parameter set.
The draft specifies that sites may define a minimum ":days" value than 1.
This implementation uses 1. The maximum value MUST greater than 7,
