Re: Cyrus IMAP, sendmail and LDAP
John, Thanks again, I wound up just using the socket map option w/ cyrus and sendmail, which seems to be working well for me.

Re: Cyrus IMAP, sendmail and LDAP
Thanks, I understand, but now, how can I go about setting up sendmail/ldap to deliver to my cyrus server, which happens to be the same name as my sendmail server.. i.e.: server name is: rabbit.domain.com my email address is: [EMAIL PROTECTED] I have an ldap entry for the user john.smith, and a cyrus mailbox for the user john.smith. If I set up ldap w/ a mailHost of rabbit.domain.com and a mailLocalAddress or mailRoutingAddress of [EMAIL PROTECTED], won't it just loop? How can I configure sendmail to deliver to my cyrus box on the same system. Am I missing an ldap attribute? Thanks.
