Hi Basheer,

1. Check if the directory /var/spool/postfix/private exists

2. Type in dovecot -n, if the configuration is correct you should see

auth default:
mechanisms: plain login
.
.
.
socket:
type: listen
client:
path: /var/spool/postfix/private/auth
mode: 432
user: postfix
group: postfix

Hi Basheer,

Make sure you have properly configured Dovecot since Dovecot is the one creating /var/spool/postfix/private/auth. Also try to restart Dovecot and check if it creates the auth file.

Please help to solve this issue

I am using Centos 5.3, we are facing following errors,

warning: SASL: Connect to private/auth failed: No such file or directory
fatal: no SASL authentication mechanisms
warning: process /usr/libexec/postfix/smtpd pid 25194 exit status 1
warning: /usr/libexec/postfix/smtpd: bad command startup — throttling

I have entered everything correctly,

client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}

Hi Consultant. After running some more tests, I’ve narrowed down my open relay problem a little and am hoping you can help.

When trying to use a RCPT TO: name@domain.COM I get: 250 2.1.5 Ok. That goes for any email address destine for any server ending in .COM.

However, if I try to email out to a .NET, .ORG .EDU etc, I get 554 5.7.1 : Relay access denied as expected. Any ideas?

Fatal: Invalid configuration in /etc/dovecot.conf

Hi dC,

We have basically the same configuration but it is working in my case. Sorry, I have no more ideas.

Looks like you are missing these lines

mydomain = yourdomain.com
myhostname = http://www.yourdomain.com
myorigin = $mydomain
