To bounce or not to bounce

Postby ut2k3 » Fri Jun 22, 2012 8:42 pm

Hi Guys,

first of all thanks for the great software. I have a strange Problem with bounces when I sent a test mailing to non existent E-Mails. When I sent a Mailing from news@mailingdomain.com (configured as Sender, Reply-To) to info@nonexistentDomain1234.de from OpenEMM (No Testuser or Adminuser) there is no bounce message arriving the INBOX of news@mailingdomain.com.

But the strange thing is that when I send from the shell for test with the following command:

Code: Select all
(echo subject: test; echo) | sendmail -Am -v -f news@mailingdomain.com info@nonexistentDomain1234.de


A bounce message appearing in my INBOX of news@mailingdomain.com


I've installed OpenEMM 2011 a few days ago on my fresh debian server with the following constellation:

External Mailserver (sending and receiving):
mx1.mailingdomain.com with news@mailingdomain.com

Configured with sendmail as a smarthost with the following lines:

sendmail.mc
Code: Select all
define(`SMART_HOST',`mx1.mailingdomain.com')dnl
FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl


and the credentials for the external mailserver are inside the authinfo

I've made some additional changes required by documentations or found on this forum listed in the following:

sendmail.mc (added/changed):
Code: Select all
DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp')dnl
FEATURE(`mailertable', `hash -o /etc/mail/mailertable.db')dnl
MAILER(`procmail')dnl
INPUT_MAIL_FILTER(`bav', `S=unix:/home/openemm/var/run/bav.sock,F=T')dnl


In oder to test I've added all possibilities of the mail domains to the mailertable:
Code: Select all
ksxxxxx.kimsufi.com procmail:/home/openemm/conf/bav/bav.rc
mailingdomain.com procmail:/home/openemm/conf/bav/bav.rc
bounce.mailingdomain.com procmail:/home/openemm/conf/bav/bav.rc
helohost.mailingsmtpserver.com  procmail:/home/openemm/conf/bav/bav.rc


(bounce.mailingdomain.com is an additional a-record pointed to the external IP of the OpenEMM-Host)

I've also added all these domains inside the mailertable to the relay-domains:
Code: Select all
ksxxxxx.kimsufi.com
mailingdomain.com
bounce.mailingdomain.com
helohost.mailingsmtpserver.com


the local-host-names is empty

only ksxxxxx.kimsufi.com is in the /etc/hosts configured to the external IP-Address.

I also created for testing a bav.conf-local because of the different Mailadress from the STMP.

Code: Select all
bounce@bounce.mailingdomain.com alias:ext_3@bounce.mailingdomain.com
MAILER-DAEMON@bounce.mailingdomain.com alias:ext_4@bounce.mailingdomain.com
news@mailingdomain.com alias:ext_5@bounce.mailingdomain.com


I think openEMM also creates the bav.conf right inside var/spool/bav/bav.conf:
Code: Select all
@ksxxxxx.kimsufi.com   accept:rid=local
ext_3@ksxxxxx.kimsufi.com   accept:rid=3,cid=1
ext_3@bounce.mailingdomain.com   accept:rid=3,cid=1
ext_4@ksxxxxx.kimsufi.com   accept:rid=4,cid=1
ext_4@bounce.mailingdomain.com   accept:rid=4,cid=1
ext_5@ksxxxxx.kimsufi.com   accept:rid=5,cid=1
ext_5@bounce.mailingdomain.com   accept:rid=5,cid=1
bounce@bounce.mailingdomain.com alias:ext_3@bounce.mailingdomain.com
MAILER-DAEMON@bounce.mailingdomain.com alias:ext_4@bounce.mailingdomain.com
news@mailingdomain.com alias:ext_5@bounce.mailingdomain.com


Did I made something that wrong? I would really appreciate to find the solution. After that is working I'll release a full HowTo for debian because the current one isn't that good (has a lot of gaps).

Does openEMM add special headers or something different that causes the Mailserver not sending an Bounce. I've tried also to send do Nonexistinguser@extistingdomain.de of one of my other servers. The Mail arrives an get rejected but there is NO bounces message arriving to the INBOX of news@mailingdomain.com. If I use the manual command on the shell or an E-Mailclient with this account for sending to Nonexistinguser@extistingdomain.de I get a bounce notification -> That's why I think its related to OpenEMM.

Thanks for your help! Feel free to ask for additional informations of my configuration

Your changes to get incoming bounces look ok to us. But your problem is too specific for guessing. You should have someone to check out your server configuration.
