Leiba Category: Standards Track Huawei Technologies ISSN: 2070-1721 July 2011 Sieve Vacation Extension: "Seconds" Parameter Abstract This document describes a further extension to the Sieve Vacation extension, allowing multiple auto-replies to the same sender in a single day by adding a ":seconds" parameter.

Introduction The Sieve [RFC5228] Vacation extension [RFC5230] defines a mechanism to generate automatic replies to incoming email messages. Through the ":days" parameter, it limits the number of auto-replies to the same sender to one per [n] days, for a specified number of days. But there are cases when one needs more granularity, if one would like to generate "vacation" replies more frequently. This extension defines a ":seconds" parameter to provide more granularity for such situations. 1.1. Terminology Used in This Document The upper-case key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. The ':seconds' Parameter The purpose of the ":seconds" parameter is to specify the minimum time interval (in seconds) between consecutive auto-replies to a given sender. The ":seconds" value, if specified, is used instead of the ":days" value, and works in a similar way (see the Vacation extension [RFC5230] for details). Only one of ":days" or ":seconds" is allowed -- use of both parameters in the same vacation action MUST result in a Sieve processing error. The capability string associated with this extension is "vacation- seconds". Note that "vacation-seconds" implies "vacation", and a script with "vacation-seconds" in a "require" list can omit "vacation" from that list. George & Leiba Standards Track [Page 2] RFC 6131 Sieve Vacation: Seconds Parameter July 2011 The time value is specified in seconds, and MUST be greater than or equal to 0 and less than 2**31. All valid values, from 0 to 2**31, MUST be accepted without error. Sites MAY define a minimum effective value and/or a maximum effective value. If a site chooses to do that: 1. Call the value specified "v(spec)". 2. Call the minimum effective value "v(min)". 3. Call the maximum effective value "v(max)". 4. Call the actual effective value used by the processor "v(eff)". 5. The following apply for determining v(eff): * If 0 <= v(spec) < v(min), then v(eff) = v(min).Show full document text
