How do other Cyrus administrators handle this > requirement? we don't use Cyrus as an authoritative source of known addresses, the information is stored in LDAP. since we support many addresses per Cyrus account (e.g. k.t.homme@xxxxxxxxxxx is equally valid for my account), we simply can't leave it to Cyrus. in Exim, you could use a recipient callout (over LMTP) to test validity of addresses. not sure how to best handle it with Sendmail. -- Kjetil T. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
