Nope, just flexible TTLs. I normally like to issue fairly long TTLs (at least, long compared to 5 minutes) -- But when I know an IP change (or more likely, a server change -- i.e. a new mail server is coming up to replace a server) is upcoming then a short TTL can reduce the changeover time to zero. -- Dave Warren, Email Address: [EMAIL PROTECTED] Cell: (403) 371-3470 Fax: (403) 371-3471 Toll free: (888) 371-3470 Vonage: (817) 886-0860 ICQ: 17848192 AIM: devilspgd Yahoo!: devilspgd MSN/PASSPORT: [EMAIL PROTECTED]
