General :: Webmin: Postfix Relayhost With ISP RoadRunner?

Jul 21, 2011

From the posts relevant to postfix I could not find the particular combination of issues I'm facing. Any pointers or references to posts will be greatly helpful. I have CentOS server running Postfix which was recently moved into my house running over TW cable (Austin RoadRunner). In Webmin -> Postfix Mail Server -> General Options - Other General Options - 'Send outgoing mail via host' (which is the relayhost) is set to:



I expected the relay to reflect this in the log but it doesn't When I send an email I see this in /var/log/maillog


Jul 21 17:10:46 cromagnon sendmail[14853]: p6LMAjlu014853: from=root, size=49, class=0, nrcpts=1, msgid=<>, relay=root@localhost

And a timeout occurs a little while later


Jul 21 17:17:04 cromagnon sendmail[14853]: p6LMAjlu014853:, ctladdr=root (0/0), delay=00:06:19, xdelay=00:06:18, mailer=relay, pri=30049, relay=[] [], dsn=4.0.0, stat=Deferred: Connection timed out with [] I basically *all* mail from all domains on this server to go through the relayhost. I understand there are a million caveats but I wish someone could help me with the basics.

BTW I've also tried to set the relayhost to



however the log still shows . . .relay=root@localhost . .

Server :: Postfix With Smarthost/relayhost On Ubuntu 10.04

Oct 16, 2010

I have been following this guide (I went through it twice actually): [URL] Since bellsouth blocks port 25 (except to their smarthost) I set up postfix with the option "internet site with smarthost" (not sure if that was exact wording). The final goal of this is to set up a couple mailing lists. When I try to test it I get:


joel@themis:~$ telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.

Server :: Postfix Relayhost Not Working, If Domain Hosted On Same Server, But MX Points Outside?

Jun 23, 2010

i compiled and install postfix, and i using relayhost that point to my ISP. but my "DNS server" is on the same server where is installed postfix. and there is running apache with vhosts so i have domain that hosted on same server and in zonefiles of my domain my MX records points to Google Apps, to google's MX servers. But when i try send E-mail via sendmail to it not deliver mail to Google Apps totally, if i try to send to another E-mail everything fine it deliver it. so finally i done research this problem in Internet. And find that need to disable deliver mail to localhost(localdelivery)as i think postfix understand that the domain point to the same server where postfix have itself. and try to deliver mail local. but zonefile MX record even the domain on same server can point to another server outside. So i disabled localdelivery in postfix. and problem not fixed

Apr 6, 2010

I have had webmin running previously but i just recently installed Unbuntu server and i am now trying to install webmin. after typing this to install webmin sudo apt-get install webmin it started doing its thing and then it halts.

Giving me the following message: "Package webmin is not available, but is referred to by another package. this may mean that the package is missing, had been obsoleted , or is only available from another source."

The first thing i did after installing webmin was edit the sources.list

Then i tpyed sudo nano sources.list I uncommented everything with "deb" in front of it

I also uncommented

deb cdrom:

I then typed this sudo wget [url]

After getting that i typed this apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

Then i tryed to install it and got that error.

I also tryed install it using this tutorial [url]

General :: Home Broadband (TWC/RoadRunner/San Diego) Intermittently Drops Out For Minutes At A Time?

Nov 19, 2010

Our home broadband (TWC/RoadRunner/San Diego) intermittently drops out for minutes at a time. In WinXP, I had a logger that would ping one or more sites (e.g., log the ping times, and display the data in an interactive graph. This was very useful in showing the ISP tech (I didn't know about Shibboleet then).The problem is still unsolved after two visits, but now I'm using Ubuntu 10.04. I'm looking for a similar tool. I'm a Linux newb (i.e. "just write a script" isn't helpful at this point), so I'm hoping for something user-friendly with a GUI.Can anyone recommend a Linux utility that...Logs ping timesDisplays results graphicallyDoesn't require advanced Linux skills to set up

Ubuntu Servers :: Webmin Dependency - Install Webmin On Edition 10.04 ?

Apr 3, 2010

I encountered a a dependency issue when trying to install Webmin on Ubuntu Server Edition 10.04 Beta1.

When you try to install webmin, libmd5-perl is not available in any of the lucid repositories:

I resolved the dependency prob by adding the following repository to my /etc/apt/sources.list: deb [url]

Then I did a sudo apt-get update then sudo apt-get install and libmd5-perl installed fine along with webadmin. BTW. I got a GPG error when doing a apt=get update because I did not import the public key for the debian repos I used to get libdm5-perl, which doesn't matter to me as I commented out the repos once I got libmd5-perl installed.

General :: User Management Possible In Webmin ?

Apr 7, 2010

I'm was wondering if there is such a feature in webmin (or perhaps any other webgui) that would solve the following problem:

I need a few people to disable/enable users in a specific group, any only in that group.

Ex: Employee A logs in to webmin to enable an user account for employee B that is a member of the group "disabled by default".

Employee A are not able to disable/enable any accounts outside the "disabled by default"-group.

Would that be possible in webmin or any other webgui?

General :: Debian 5.0 Ffmpeg Unmet Dependencies - Webmin?

Mar 24, 2011

I am running a video script on my server and I am very new to running a dedicated server and commands. Most of our site was setup but other and someone has broke something and no one seems to know how to fix.

Here is the issue. We run a script that uses these requirements

[Mod edit]Adult content Link removed


Now our server guy ran a update inside webmin for debian and now our videos still convert but wont make thumbs. Here is what he did.

Now updating libsmbclient ..

Now the AVS script wont make thumbs and webmin still wants to do 3 more updates that get unmet dependencies errors. Here they are when we try to run another update.

Building complete list of updates ..

Now what we need to do is either undo the update he already did or maybe get the one its asking for now to work but not sure which one will fix our thumb generating problem? Here is the error in the log file of the AVS script.

Seems stream 0 codec frame rate differs from container frame rate:

General :: Using Webmin: Added Allowed Host IP Address

I am using Webmin to access a database. I finally acquired a static IP address. After entering it into the allowed host for the PostgreSQL server, I still can't access it through the SQL Manager for postgres in Windows. It doesn't seem to actually make the change. I am the new person managing this database. The old person use to be able to just add an IP address and it would connect. Is there something I am missing that I may need to install?

General :: Servers On Same Subnet / Same Iptables / Can't Access Webmin On One

Apr 8, 2010

Two servers, one is RHEL 4, and the other is RHEL 5. They are both on the same subnet, one is 10 the other is 11. I added the Webmin rule to the iptables config file but for some reason, the RHEL 4 server, I can access Webmin but the RHEL 5 server I can not. I checked the iptables file and they are the same for both servers, except two rules which are for other ports.

I'm reading about the iptables and had a problem when I manually added the port 10000 entry after the REJECT entry, but wondering if I need to move it up higher or maybe there's another possible block?

so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

Server :: Updated Postfix Not Running After Transferring Over Users From Older Postfix?

Feb 25, 2011

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:

Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied

I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.

Programming :: Conversion From Infix To Postfix And Compilation Of Postfix For Eval

May 11, 2010

I was trying to write a graph plotting program with c++. I need to convert the infix expression from user to postfix expression for quick evaluation. However, the evaluation of postfix is kind of interpreted, and thus kind of slow for evaluating huge number of values. Say if I plot an implicit function the penalty is quite huge. Is there a way that I can compile the infix expression from my running graph plotting application for high speed evaluation.

CentOS 5 :: Switch From The Default Sendmail To Postfix Doing A Yum Install Postfix On 5.2

Dec 12, 2008

I have isntalled a server with Centos 5.2 OS, now I would like to switch from the default sendmail to postfix doing a yum install postfix I've noticed there is already available an rpm version for the OS but I would like to compile my own 2.5 version, I've noticed compiling from source does not allow me to use the mail switcher to tell to the system I'm gonna use Postfix instead of Sendmail as the default MTA while this is possible when I use the "official" rpm version of the package. Now my question is this, would this be a problem? There is some specific procedure/best practice I should follow? Or once compiled and configured Postfix I can safely disable/uninstall sendmail?
