[Dovecot] howto disable indexing on dovecot-lda ?
Hello, is it possible to disable indexing on dovecot-lda ?
Right now postfix delivers the mail directly to the nfs server without any problems. If I switch to dovecot-lda the system crashes do to the high I/O and locking. Indexing on lda is not very useful because the number of of imap logins is less than 5% that of incoming mails, so an user could wait for 3 sec to get his mail index, but a new mail can't.
Dovecot version 1.2.15 mail_nfs_storage = yes mail_nfs_index = yes
Than you !

Disabling indexing won't disable writing to dovecot-uidlist file. So I don't know if disabling indexes actually helps.

I don't have mail_location under "protocol lda":
protocol lda {
Address to use when sending rejection mails.
postmaster_address = postmaster@xxx sendmail_path = /usr/lib/sendmail auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota syslog_facility = mail }
The mail_location is present only global. What to do then ?

I don't have mail_location under "protocol lda": Just add it there.
Thank you ! Dovecot didn't complain after restart and the "dovecot -a" reports it correctly:
lda: postmaster_address: postmaster@xxx sendmail_path: /usr/lib/sendmail auth_socket_path: /var/run/dovecot/auth-master mail_plugins: quota syslog_facility: mail mail_location: maildir:/var/virtual/%d/%u:INDEX=MEMORY
I will do a test with this.

Then why bother with Dovecot LDA w/disabled indexing (the main reason for using it in the first place) instead of simply sticking with Postfix Local(8)?

Because of sieve and quota support. Another possible advantage will be the support for hashed mailbox directories.
Hello,
I tested with "mail_location = whatever-you-have-now:INDEX=MEMORY" and it seems to help, but in the mean time I found another option completely undocumented that seems to do exactly what I wanted: protocol lda { mailbox_list_index_disable= yes
}
Does anyone knows exactly what "mailbox_list_index_disable" does and if is still available in 2.0 and 2.1 branch ?

mailbox_list_index_disable does absolutely nothing in v2.0, and it defaults to "no" in v2.1 also. It's about a different kind of index.
