Server :: How To Set Sendmail To Allow Authenticated Relay?

Aug 11, 2010

I have a CentOS server, and am using Sendmail to relay for various domains. However, I also need to have users send their outgoing mail via this server. I want to have them enter a username and password in Outlook, Thunderbird, etc in their smtp server settings. I currently have this set up via an Exchange server, but I cannot get it to work with Sendmail. I know little about Sendmail, and have done all the config via Webmin, which has worked fine as far as relaying domains. But even though I have added the CentOS user account for the smtp relaying, the clients mail apps give an error saying relaying denied.

Server :: Sendmail Relay Messages To Ext. SMTP Server?

Jan 31, 2010

I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

Server :: Sendmail Forward Copy To Another Mailbox?

Apr 7, 2011

We're using sendmail with ldap routing. We've setup a new mailstore which some of our users are piloting.

We've been asked to configure sendmail to forward a copy of pilot users emails to the new mailstore (Zimbra) as well as the old (Sun Messaging).

I'm not exactly sure how to do this. I've tried modifying aliases to forward to 2 destinations, but ldap routing seems to take precedence before aliases.

Networking :: Relay Raw ICMP Packet To Local Destination

Feb 21, 2011

On my system, I have built my own tunneling protocol, where I relay packets over a non-standardized but verified medium. What I do is capture the packets using iptables and NFQUEUE, relay them over my medium, and at the other end I reinject them using raw sockets. The packet going into the tunnel is exactly the same as the one coming out, verified. The problem is that this doesn't work for ICMP Ping (Echo Request) if the destination of the ping is the same as the tunnel endpoint. If the destination is not the same as the tunnel endpoint, the ping packet is rerouted and arrives as it should at the receiver, and the ping reply comes back to the sender. Does anyone know whats going on? Isn't it possible to send raw icmp to yourself? If not, anyone have an idea what I should do instead?

General :: Update Svn Working Copy Via Cron When Its Server Located On Local?

Aug 3, 2010

I have two servers. One of them has a svn server running and another hosting projects.

I have a daily cronjob updating the projects -- ie running svn update, rebuild etc.

Now, my cronjob on the remote server works.
However, a similar cronjob running on the local server for local projects (ie the same server as svn) is instead displaying a "svn: not working copy".

I double checked the paths, permissions and user info and if the script is launched manually, it works fine.
Deploying the same thing remotely works.

I even tried using file:/// (suggested here http://www.hightekhosting.com.au/myaccount/knowledgebase/90/Using-SubversionorSVN-on-cPanel-Servers.html) but still nothing.

Ubuntu Servers :: Mail SMTP Relay / Copy All Traffic To Another Port For Monitoring?

Sep 2, 2010

I'm running ASSP on Ubuntu 10.04.1 it's mostly working fine. I have one problem which has been bugging me for some time. I don't want to filter outbound mail, but if I can relay (proxy) my outbound mail through ASSP, then it can automatically add to the whitelist.

As ASSP is a proxy, I need a server to send it to once ASSP receives it. I've tried my ISP, but this failed and they weren't willing to confirm if a connection attempt was received at their end.

Current setup

Inbound

mx -> router -> ASSP -> Exchange 2003

Outbound

Exchange 2003 -> mx

I'd like to setup outbound as either

Exchange 2003 -> ASSP -> <ISP> SMTP relay
Exchange 2003 -> ASSP -> <relay running on Ubuntu eg postfix>

Can anyone help me with troubleshooting steps or a better suggestion for how I can set this up. I'd love to know why my ISP setup didn't work, but I don't know a tool for monitoring IP traffic in Ubuntu SE, in windows I use Wireshark is there any equivalent I can setup for Ubuntu or a tool I can use in windows which will show all traffic, Ubuntu and windows server are on the same netgear switch, not sure it's smart enough to copy all traffic to another port for monitoring.

Fedora Servers :: Fedora 10 - Sendmail / Dovecot Relay

I can then reply from both of those accounts back to the server, no problem.

The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have

Server :: Sendmail Not Reading Default Sendmail.cf ?

Apr 1, 2010

I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.

So in other words, the following works great:

However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:

I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.

Why sendmail is not reading my sendmail.cf?

I'm running Sendmail version 8.14.2 on Fedora Core 8.

Networking :: Sendmail - Change Domainname Local Users

Mar 26, 2010

I have the following problem and tried (almost) anything to fix it but without a full success.

We're running a server with CentOS 5.4. Every night a logwatch report is send. These mails are rejected by our mailserver because some invalid details. These mails are send to local user root which is redirected to another external mail address with /etc/aliases.

At first the mail was send from root@localhost.localdomain to root@localhost.localdomain. As you can imagine, our mailserver rejected this because the localhost.localdomain parts. So I changed the sendmail config with these options:

Code:
dnl EXPOSED_USER(`root')dnl
FEATURE(masquerade_envelope)
MASQUERADE_AS(`domainA.com')
MASQUERADE_DOMAIN(`localhost.localdomain')
MASQUERADE_DOMAIN(`slave02.domainA.com')

This solved my problem partially: Mail is now coming from root@domainA.com (which is OK), but is send to root@slave02.domainA.com (slave02 is the local hostname), which is not OK. I tried everything I could find to change that last part to, but nothing seems to work.

Fedora Servers :: Sendmail Delivery To Local Boxes

Jun 1, 2009

I have fedora running as our email server at work using sendmail. It used to have spamassassin and MailScanner installed, but one of those died over the weekend and killed the mail server. We do not need either of these as we are using a web based spam filter now (postini), so I tried removing these. I have discovered that the mail is in the mqueue waiting for delivery to the users mailboxes. I have tried using "sendmail -q -v":

Code:
Running /var/spool/mqueue/n51Jx6Gg023820 (sequence 1 of 1174)
<abaughman@grandproductsinc.com>... Connecting to local...
<abaughman@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL

Running /var/spool/mqueue/n51JsuRe023619 (sequence 2 of 1174)
<ksullivan@grandproductsinc.com>... Connecting to local...
<ksullivan@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL .....

I do not have a procmail config file: /etc/procmailrc. I am not sure why, or what it should be, perhaps that is the problem. I guess I don't exactly know how this server runs all that well. I was able to get it up and running but never understood it enough to now find what is not working correctly.

Fedora Servers :: Migrate Local Users And Sendmail Mailboxes?

Apr 21, 2010

I found 2 previous posts, one from 2005 and one from 2006. The 2005 post was not very helpful and the 2006 threads are not exactly what I was expecting. So I wanted to ask the question to be sure. I have already stood up the new fedora 12 server. The old server is also fedora 12. I need to migrate local users and sendmail mailboxes. In the past couple of years the environment was small enough to create a copy of the users and then have the users mail themselves, but I want to start migrating users/mailboxes properly.

On a unix level I am a jr admin, but I have extensive senior level experience as a windows engineer and network engineer. I do feel comfortable with using the unix command line, but usually operate the unix systems thru webmin because I am not familular with more complex commands. Ideally a software solution to migrate users and/or mailboxes from one server to another is what I am looking for, but in leiu of a software solution I still need to migrate user accounts and their mailboxes. LDAP is not in place, but if the process becomes easier with LDAP I am willing to do what is needed to set up LDAP. (I have no previous experience setting up LDAP)

I do not want to change my mail server from sendmail to different software. At least right now. Both systems are up and running. They can connect to each other via public ipv4 address' only. The new server has already been installed and configured with all the software to match the old server. How do I migrate users and sendmail mailboxes from one fedora 12 server to another fedora 12 server?

CentOS 5 :: Configure Sendmail To Accept Email Without Domain In Local-host-names

Mar 23, 2011

dammit... all that typing and I hit the wrong "submit" button. *sigh*

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.

SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
