References: X-Mailer: MIME-tools 5.508 (Entity 5.508) Content-Disposition: inline X-RT-Interface: Web Message-ID: X-RT-Original-Encoding: utf-8 Content-Transfer-Encoding: binary MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset="utf-8" RT-Send-CC: Content-Length: 359 This looks okay. I made a few stylistic tweaks (we already had macros for checking ZEROTTL and NEGATIVE and I thought it would be more readable to use them). If there's an NXDOMAIN flood and we're getting a lot of negative records put on this end of the list, will this in any way affect handling of the ZEROTTL records that would've been there there before?
