Most of the time was spent discussing the use of the 'mail' attribute for lookups. The consensus was that this is just an informational field used for whitepages style information. The addresses used for matching should all be listed in a multi-value attribute, notably the current 'mailAlternateAddress' attribute in the draft. Suggested names include 'mailRoutedBy', 'userMailAddress', and 'LocalMailAddress'. We also need to decide whether to do lookup in LDAP for a particular address.
Some current implementations lookup every recipient address.
The group discussed whether or not both 'mailHost' and 'mailRoutingAddress' are both needed or if everything could be accomplished with just the latter. We agreed that in order to change the destination host without changing the envelope recipient, both were necessary. The final draft issue discussed was when to lookup MX records on the returned values. Although not fully decided, it was suggested that MX records would always be looked up. After finishing lunch, we discussed the need for a working group for the remaining work.
