I've had this problem before, but the usual fixes wont work. I made a copy of a workin virtualmin box (virtualized) However, on the new webserver no mail is recieved:
i've changed the hostname in this output to 'host' and obfuscated IP's etc.
[root@host ~]# tail -f /var/log/maillog

I already tried changing my hostname in /etc/hosts and have added the '-r' option in /etc/sysconfig/saslauthd.

I guess we'd need some more information. What exactly did you try when the error occurred? Anything in the auth log?
i've tried sending a mail to the test@testdomain user on this system from myemailaddress. It bounced (undelivered mail returned to sender) with a 554 5.7.1 error.
what do you mean wihth the 'auth' log?
Howdy,
The auth.log file is an awesomely helpful logfile on Ubuntu/Debian... CentOS, which it looks like you're using, doesn't use that though :-)
However, I suspect the issue is something in this line in your Postfix config:
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_non_fqdn_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unauth_destination, reject_unauth_pipelining, reject_invalid_hostname, reject_rhsbl_client blackhole.securitysage.com, reject_rhsbl_sender blackhole.securitysage.com, reject_rbl_client zombie.dnsbl.sorbs.net, reject_rbl_client relays.ordb.org, reject_rbl_client opm.blitzed.org, reject_rbl_client sbl.spamhaus.org, reject_unknown_reverse_client_hostname, permitIf you change that back to the default (temporarily, at least), are you then able to send an email?
The default line looks like this:
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destinationAfter changing that, restart Postfix:
/etc/init.d/postfix restarttried, no change. And as I noted, the main.cf is a copy from a working virtualmin server... I'm using @ in usernames (and changed the virtualmin settings accordingly), but on the other server it works without problems.
according to http://nixcraft.com/centos-rhel-fedora/13804-enable-auth-log-authenicati... the auth log is /var/log/secure under CentOS. I've checked this log, but no errors are reported.
Ano other suggestions?
Hi,
What did you do just before this issue presented itself?

I've imported the virtual machine into another hypervisor :) Then I added a new domain and tried importing a backup. In both cases mail would not be delivered.
I finaly found it. in master.cf this line was present:
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
changed it into
-o smtpd_client_restrictions=permit_sasl_authenticated,permit
I think it had something to do with the other server on which I used smtpd authentication. Don't know why it workes on the other server though.
