Scalix Forums

We currently do not appear to be able to run Scalix and Sendmail at the same time. It appears that whichever one gets launched first attaches itself to port 25 and prevents the other one from also attaching to the port.

As you can see in the example below with sendmail running it is the only thing listening on port 25. If I shut it down then nothing is listening, a restart of Scalix allows it to listen, but now if I start sendmail it no longer listens on port 25.




Can anyone suggest why these programs are not getting along with each other.

I also ran the following :



This seems to suggest a problem with SMTP relay. I edited var/opt/scalix/<ff>/s/sys/smtpd.cfg to turn on the Debug log, restarted the SMTP Relay and here is the entire log file recorded :


However omstat still reports SMTP Relay as Partially Abor.

Any help welcome.

Cheers.

You probably still have sendmail listening on the external IP. Modify sendmail.mc to listen only on the loopback 127.0.0.1 and regenerate the sendmail.cf file. Then restart everything again and it should work.

I have the following in my /etc/mail/sendmail.mc



From reading that it appears my sendmail should only be listening to the local loopback.

Swordfish : if you were referring to a different part of the sendmail.mc file can you let me know.

Thanks.

Hi!

For me it is:

dnl #
dnl # The following causes sendmail to only listen on the IPv4 loopback address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

I've made that change, remade the sendmail config file, restarted sendmail, Scalix and Scalix-Tomcat and still I only see sendmail attached to port 25:



A look at Scalix's status also shows something still amiss with SMTP Relay :



Any further ideas or any more info you need from me?

Cheers.

Let's first verify that sendmail is only listening on the 127.0.0.1 interface:

Do the following: telnet 127.0.0.1 25 and post the response (change your server real name)

Then: telnet x.x.x.x 25 (where x.x.x.x) is your server IP address and post the response as well.

please provide a

Hi!

I would first suggest you to backup sendmail.cf to aviod crisis using the command:

Coming back to the current issue,
The 127.0.0.1 line is required to allow outgoing mail to be processed, as below:

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

I would suggest you to edit the sendmail.mc to change the line in your server from:

dnl # The following causes sendmail to only listen on the IPv4 loopback address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp, Name=MTA')

to

dnl #

dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Rebuild the sendmail.cf file using the command below:

After rebuilding the sendmail.cf file from the sendmail.mc file, all of the Scalix changes
are lost and thus mail is no longer flowing, to correct this, run the command:

Now, restart sendmail and smtp relay using the commands below:
Stop and start sendmail:

Restart SMTP Relay:

Check what result you get for the command "lsof -i:25", ideally this should look like:

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
sendmail 17999 root 3u IPv4 115968 TCP localhost.localdomain:smtp (LISTEN)
omsmtpd 18027 root 5u IPv4 116050 TCP subir-rhel4.scalix.co.in:smtp (LISTEN)

While the result for command "omstat -a" should return:

SMTP Relay Started

Hope this helps you.

Thanks,
Subir

Swordfish : as requested here are the results of using telnet :



Florian : here are the results of lsof. As you can see only sendmail is registered against port 25.



Subir : here are the results of the process you suggested :




As can be seen the SMTP relay still has a problem. From a variety of experiments with lsof, stopping and starting both Sendmail and Scalix the first program started gets assigned to port 25 and the second one to be started is unable to do the same. I can have Scalix running on port 25, or I can have sendmail running on it, but not both at the same time. See the example below where the order of starting the services determines which program gets registered against port 25 :



Thanks to you all for your continuing help on this.

Hi Again!

No worries, lets try further, what is the value for domain, in /etc/sysconfig/sendmail file?

Thanks,
Subir

The entire /etc/sysconfig/sendmail file reads :



No mention of domain.....

it is not the domain setting - the issue is that your sendmail is listening on the external ip address, which shouldnt be the case.

i should have asked this earlier - what OS is this? redhat? suse? somethng else? what version?

Thanks,
Florian.

We are running Fedora 5.

can you post your /etc/mail/sendmail.mc?

Florian.

As requested /etc/mail/sendmail.mc :



Cheers.
