Server :: Force Sendmail To Route All Mail To Another Host

Jun 14, 2011

It has been years since I had to mess with sendmail (I prefer using postfix) - but I inherited a server that someone else configured. This machine is a webserver - but is running sendmail for the various webforms, etc. I want to configure sendmail on this machine to route ALL outgoing messages to the main email server. This means local users too. I have read through sendmail configurations for the past 3 hours, but it's mostly greek. Here is my current sendmail.mc file - could some kind soul tell me what I need to change (and WHERE)?

Server :: Sendmail: Block Specific Sender To Specific Recipient?

Oct 1, 2009

I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.

Red Hat :: Sendmail No Route To Host

Jan 15, 2010

I have two machines: A.domain.com: (Old mail server): Red Hat 9 (Linux 2.4.20-30.9) B.domain.com: (New mail server): RHEL Client 5 (2.6.18-164.2.1.el5) (Both machines are in the same subnet and on the same switch). I wanted to test the new mail server by sending an E-mail message to it from the old one, but the maillog says

[code]...

I can ping from A.domain.com to B.domain.com and from B.domain.com to A.domain.com . I can traceroute -p 25 from A.domain.com to B.domain.com and from B.domain.com to A.domain.com. I can *telnet* on port 25 from B.domain.com to A.domain.com. BUT when I telnet on port 25 from A.domain.com to B.domain.com. I get "telnet: connect to address x.x.x.x: No route to host". The resolved IP x.x.x.x is correct by the way. So I see no reason why. it should fail to telnet on port 25 to A.domain.com.

General :: How To Configure The Sendmail

Jan 15, 2011

I have a apache server installed on my system which I use for testing out stuff like wordpress and forums. I use the server for learning stuff only. I would like to know what do I have to do so that these blogs, forums etc can send an email when someone registers. I guess most of these use sendmail to send email. So how do I configure sendmail so that it sends email using my gmail address and smtp. Also I think there is a php mail option (or something called like that) that allows us to send email without having sendmail installed.

Server :: Sendmail Can't Send To Some Hosts Timeout Error / Fix It?

Sep 12, 2010

I'm running sendmail 8.14 which sends out thousands of email. I'm getting several timeout error on only a few particular hosts. What I found is almost all of them are Exim 4.69

maillog shows
--> timeout waiting for input from ..@xxx during client greeting

after several tries, I finally got bounce back with

--> 451 4.4.1 reply: read error from xxx.com.
.. Deferred: Connection timed out with xxx.com.
Message could not be delivered for X day
Message will be deleted from queue

When i search though maillog with all of those error and they all seems to be running Exim and they are different mail domains.

Networking :: Route Add With Specific Interface?

Apr 18, 2009

I have an Asterisk-server with 2 interfaces, a WAN-interface (eth1) and a LAN-interface (eth0).

SETUP : IAX-provider(internet) --> firewall --> Asterisk-server --> switch --> clients_on_LAN

So everything coming from the IAX-provider on port 4569 is forwarded to the Asterisk-server's WAN-interface (eth1). This needs then be routed to an internal SIP-phone (an IVR-system will define which one) via eth0. When a call is initiated from an internal SIP-phone (they register to the IP-address assigned to eth0) it needs to be routed via eth1 to the gateway (192.168.4.250). Asterisk will setup an IAX-channel on WAN-interface (eth1) to the IAX-provider (via gateway). So... will this work :

Code:

route add -net ip_IAXprovider netmask 255.255.255.0 gw 192.168.4.250 dev eth1

Code:

route add -net 192.168.4.0 netmask 255.255.255.0 dev eth0 (no gateway needed for the LAN-interface, communications to the gateway need to go via the WAN-interface !)

General :: Configure Sendmail (Serve Two Domains) For Slackware

Apr 19, 2010

I'm configuring sendmail that runs on Linux Slackware but find some difficulties to do some quick startup due to its complexity and massive documentation. Suppose I want to configure a sendmail that can serve 2 domains:
ethereal1m.no-ip.com
ethereal2m.no-ip.com

I use noip2 client software to connect with noip server that translates the dynamic IP addressed domains, setups POP, and does forwarding. By having 2 domains, I want to able to send email between admin@ethereal1m.no-ip.com and admin@ethereal2m.no.ip.com;therefore, my machine acts as both a server and a client. How can I setup sendmail so that it acts as both server and client? How to register email address and its domain on sendmail?

I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:

Networking :: Route Only For A Specific Port And Target?

Mar 14, 2011

I have to route some packages over the right interface.I default route everything for the target-network over one network-interface. That works perfectly. But i have to route packages for one specific host and one specific port over another network-interface. I tried many things with the route-command, but i think there's no possibility to route only one port? May i can do this with iptables? I only found ways to forward some packages, which are coming in over one interface. But in my case all packages go out over one interface.

Networking :: Trace Route On A Specific Port?

Dec 4, 2009

I've got a few systems which forward ports to one another all over the place, and somewhere along the line a port forward fails. I want to trace the route of a connection on a specific port to see where the connection hits a wall, to see what system is causing the problem. I've tried `tracetoure -T -p <port>` but it doesn't output anything about the ports it hits, stops when it hits the address I supplied even though it is forwarded elsewhere, and there doesn't seem to be a verbose mode. interstingly, if I specify a different source port via the '-s' option, the trace keeps hopping to * * * * and never get anywhere (at least to 27 hops then I CTRL+C)
