Re: [WISPA] Postfix/Dovecot Experts
Ok... I fixed it. We were using PAM using LDAP for the authentication for SMTP and just LDAP for Dovecot (imap/pop3). I found an article on how to set SMTP to use Dovecot as the authentication source for email so I just change the LDAP settings in one place. http://www.linuxmail.info/postfix-smtp-auth-dovecot-sasl/ That sped my lookups up when the "auth" line goes through, instead of being 30 seconds to more than a minute to less than a second. Thanks for all the input, but I thought I would pass it along that it was fixed. I did check and I am not using any RBLs, the failure was on the authentication. I did check DNS entries and made sure everything is going through successfully.

Re: [WISPA] Postfix/Dovecot Experts
Are you using a DNSBL that doesn't work anymore or that is blocking you? Is the delay before or after the banner, and if after, at what point? Have you tried doing an SMTP session by hand with telnet to see where the delay is? -Kristian On Mon, 2010-03-22 at 16:33 -0400, Eric Rogers wrote: > I have a CentOS box that uses LDAP to authenticate my POP3/IMAP/SMTP > queries to my Active Directory server.

Re: [WISPA] Postfix/Dovecot Experts
Double check that you have both a reverse and forward DNS entry. Also make sure identd is turned off. -Eric On Mon, Mar 22, 2010 at 1:33 PM, Eric Rogers wrote: > I have a CentOS box that uses LDAP to authenticate my POP3/IMAP/SMTP > queries to my Active Directory server.
