I remember reading about this somewhere before, so if you can find the reference please post it:
What's the _preferred_ action to take when trying to establish an IP address for a remote server while doing s2s dns lookups? So eg: looking up the server to send a message to [EMAIL PROTECTED] should result in: SRV IN _xmpp-server._tcp.department.example.com SRV IN _jabber._tcp.department.example.com (optional) SRV IN _im._tcp.department.example.com (optional) AAAA IN department.example.com (optional) A IN department.example.com then if those all fail do/should/must/may/shouldn't/mustn't we try: SRV IN _xmpp-server._tcp.example.com SRV IN _jabber._tcp.example.com (optional) SRV IN _im._tcp.example.com (optional) AAAA IN example.com (optional) A IN example.com and then: SRV IN _xmpp-server._tcp.com SRV IN _jabber._tcp.com (optional) SRV IN _im._tcp.com (optional) AAAA IN com (optional) A IN com Most jabber servers seem to give up and _not_ do the dns cascade, but Wildfire seems to do the cascade DNS, generating lots of 'Failed to lookup .de', or 'Failed to lookup .org' records in the log files. ref: http://www.jivesoftware.org/community/thread.jspa?messageID=123998 -- - Norman Rasmussen - Email: [EMAIL PROTECTED] - Home page: http://norman.rasmussen.co.za/
