Do you already have a large number of records in your ldap database?

It’s mot a hardware problem . Now I’m running qmail + vpopmai on the same hardware and with no problem.

Hi Catalin,

 

You can also have a check with your hardware, especially the disk IO. I had experienced problems such as this before on a production mail server I am maintaining and found out that the problem was due to a faulty disk array installed on the server.

Hello

 

I have the following setup: openldap 2.2.36 qmail-1.03 + qmail-ldap-1.03-20050401a , courier pop3 + imap (with authlib latest version).

The ldif looks like this : --ou=administrators

                                      --ou=Groups

                                                --ou=Domain1.com

                                                     [EMAIL PROTECTED] (this is a qmail-group for mailing list)

                                                --ou=Domain1.com

                                                    [EMAIL PROTECTED] (same for domain2.com)

                                    --ou=Users

                                                --ou=Domain1.com

                                                     --ou=a

                                                            [EMAIL PROTECTED]

Etc.

 

The messages in queue takes too long to be delivered to users Maildir , I’ve turn on debugging for ldap and qmail does one search for mail address and the stop (unbind) for 2 sec and the starts all over again for the next mail.      I know that persistent connection is not an option with openldap , but for what I have read this setup (openldap +qmail-ldap) is one of the fastest and I this that I’m doing something wrong . Please give me an advice .
