Sendmail.mc

Hi Timo,

Thnx for quick suggestions, however i am still in trouble. I am using FS Quota and mbox. After looking at the Quota/FS, I changed the mail_location to below. Few of my dovecot.conf settings are:

mail_location = mbox:~/mail:INBOX=/home/%u/mail/INBOX:INDEX=/var/mail/indexes/%u

protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster@localhost mail_plugins = quota }

Plz suggest what to do next ......

Regards -Azher

Hi,

I am using dovecot deliver as lda for sendmail. My problem is that when a user account is over quota, deliver program sends message in the logs, but the message is not bounced back to sender informing that their is disk quota problem at the recipient side. Further message remains in the mail queue. Details are below. Plz suggest how to figure out the problems:

It failed with EX_TEMPFAIL, so Dovecot didn't properly handle the out-of-quota condition. You're using filesystem quota I guess? If you're also using maildir, that won't work if your control files are in quota partition. See http://wiki.dovecot.org/Quota/FS

I am using the latest version 1.0

This is the output from mail.log

Hi Timo,

Thnx for your time replying me. I did the steps as suggested on the link and here are the details now. IMAP, SSL , POP3 SASL, IMAP-QUOTA etc .. everything works perfect but the LDA is still giving the same error, details are below:

So deliver doesn't work at all, and it has nothing to do with quota?

You'll need to set up the auth-master socket as http://wiki.dovecot.org/LDA explains.
