Sendmail - issue within DMZ for some servers but not all
Hi All,
I have a strange issue and I am not sure where the problem lies.
I have about six Ubuntu servers on our DMZ two of which were built on 18.04 from scratch the others were upgraded to 18.04 from 16.04.
The servers built from scratch can send emails from the server via sendmail fine, so the Firewall rules for coming from DMZ to our internal network is fine.
The servers upgraded to 18.04 cannot send out emails, it is as if sendmail does not work.
This is what I get
I have uninstalled & purged sendmail from a server that does not work and re-installed.
I have updated the sendmail.cf to point to the mail server
the Hosts file has the relevant info...
It still does not work...
could someone help or point me in the right direction?
I am having the same issue on all systems in the DMZ that have updated from 16.04 - 18.04

sm-archive
SM-ARCHIVE(1)SM-ARCHIVE(1)NAME
sm-archive - a sendmail milter to add recipients to messages
SYNOPSIS
sm-archive [-c] [-d n] [-p sendmail-socket] [-t timeout]
OPTIONS -c Load the configuration file, print a cannonical form of the configuration on stdout, and exit.
-d n Set the debug level to n.
-p sendmail-socket
Set the socket used for the milter connection to sendmail. This is either "inet:port@ip-address" or "local:local-domain-sock-
et-file-name".
-t timeout
Set the timeout in seconds used for communication with sendmail.
USAGE
sm-archive -c
sm-archive -d 10 -p local:sm-archive.sock
INSTALLATION
This is now a standard GNU autoconf/automake installation, so the normal "./configure; make; su; make install" works. "make chkconfig" will
setup the init.d runlevel scripts. Alternatively, you can use the source or binary RPMs at http://www.five-ten-sg.com/sm-archive/packages:
http://www.five-ten-sg.com/sm-archive/packages.
Note that this has ONLY been tested on Linux, specifically RedHat Linux. You will need at a minimum a C++ compiler with a minimally thread
safe STL implementation. The distribution includes a test.cpp program. If it fails this milter won't work. If it passes, this milter might
work.
Modify your sendmail.mc by adding the following line in your sendmail.mc and rebuild the .cf file
INPUT_MAIL_FILTER(`sm-archive', `S=local:/var/run/sm-archive/sm-archive.sock, F=T, T=C:30s;S:5m;R:5m;E:5m')
Modify the default sm-archive.conf(5) configuration.
CONFIGURATION
The configuration file is documented in sm-archive.conf(5). Any change to the config file, or any file included from that config file, will
cause it to be reloaded within three minutes.
INTRODUCTION
Consider the problem of archiving all the mail sent to or from particular email addresses or domains. This milter allows you to configure
archive mailboxes for each address or domain. It will add the address of the archive mailbox to messages that pass thru this milter.
The archive milter reads a text configuration file (sm-archive.conf) on startup, and whenever the config file (or any of the referenced in-
clude files) is changed. The entire configuration file is case insensitive. If the configuration cannot be loaded due to a syntax error,
the milter will log the error and quit. If the configuration cannot be reloaded after being modified, the milter will log the error and
send an email to root from sm-archive@$hostname. You probably want to added sm-archive@$hostname to your /etc/mail/virtusertable since oth-
erwise sendmail will reject that message.
TODO
Placeholder for future ideas.
