We run Postfix in front of an Exchange 2003 box. I currently run a cron job every hour to pull a list of valid email addresses of users (and all associated aliases) and Public Folder email addresses down from the Exchange box.
Whilst we don't add/remove addresses terribly often, it's a guaranteed way of making sure that any new accounts/email aliases are accepted quickly if they're setup whilst I'm not here. I wondered how simple/difficult (I'm not new to Linux but would count myself as a "know what I need to get by" type) it would be to have Postfix do an "on the fly" ldap query and just have it cache the results for a period of time rather than each and every hour have it download an entire list of email addresses? I've had a look at the docs and Google and I'm struggling to find a "one size fits all" guide. Thanks in advance. Paul -- MIRA Ltd Watling Street, Nuneaton, Warwickshire, CV10 0TU, England.
