My company is changing it's mail subdomain...Example: [URL]. I wanted to build a sendmail box up to handle this until all the sending parties get the new address. I'm sure it's in the rewrite hearder part of sendmail.cf but I just don't understand how to doit.
View 2 RepliesI have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?

We have MS Exchange email server with postfix/amavis on FreeBSD as proxy for anti-spam and anti-virus. We use our own developed CRM and trying to implement such functionality that when CRM manager send email to CRM client or vice versa through email client like Outlook (no plugins for CRM) this message would be shown in CRM. There is already a solution to parse emails from specific emailbox and show it in CRM.
What I need is to create postfix email filter to check if sender email is in file CRM_managers_emails and recipient email is in file CRM_clients_emails then forward that email to [URL] Filter should check both incoming and outgoing messages. I will auto generate CRM_managers_emails and CRM_clients_email files containing all such emails taken from CRM database. I know i should use something like Postfix After-Queue Content Filter but most of examples are for blocking emails.
In my Windows environment, I use email client such as Microsoft Outlook to connect to our email server to send email with the following configuration:
Incoming server (POP3): 995 - (requires with SSL)
Outgoing server (SMTP): 465 - (use encrypted connection SSL)
[code]....
And the mail server requires user ID login and password.how do I setup a text command based email client in my Linux (Centos 5.1) to send out email through the existing email server above, which is in another machine? The email client has to be text command based because I need to use command line to send notification email from anothar application installed in my Linux (Centos 5.1) Since the email client will only be used to send email notification, I don't require setting up of an email server in my linux.
Using CentOS. I have a cron setup to run this command: Code: /var/test.sh | mail -s "Test Cron" mr182@somewhere.com The email is sent but the output of the script is not in the email body, it's just blank. I know there is some output because there are some echo statements in the script.I don't want to get an email for all cronjobs, just this one.

My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface.
If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command.
Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

My router has two bridges, br0 and br1. I'm sharing wifi access, and the guest subnet will be 192.168.2.x.The home subnet will be 192.168.1.x. I want all traffic destined for port 80 from the guest net to forward to a proxy port on a box on the home network. That's the only traffic I want to cross the bridges. How do I set this up with iptables on the router?

View 2 Replies View RelatedI have a (virtual) server with 3 NIC's: 1 external (inet), 1 local and 1 DMZ. This server is my gateway.
I would like my internal network, where every server has a static 192.168.0.x IP, to access the internet via the gateway.
That means the traffic has to pass from the 'local' NIC to the 'external' NIC, connected to the internet.
Which setting do I change to accomplish this ?

I've always been curious about this but say that you had computer A which runs headless and had music that you wanted to hear from computer B. Sure you can setup vlc or icecast on computer A and stream it. But what if you could forward the sound over netcat. For example, say when you play a sound file on Computer A data gets sent to /dev/snd.Would be possible to do something like the following.
Computer B
nc -lvp 6666 > /dev/snd
Computer A
cat /dev/snd | nc -v -w 5 computer_b 6666
And be able to hear sound playing on Computer A? point me in the right direction to find out about how to do this?

View 1 Replies View RelatedI notice that my bittorrent client is capable of automatically setting up port forwards with my router, and I want to know if I can do the same in a shell script. The reason is, that since my router is stupid and won't let me keep static IP addresses (it seems they forced a DHCP refresh every week to make me want to pay for a more expensive model which doesn't), I need to get my computer to change the port forward to follow my computer's changing internal network IP address. I have a couple of port forward manually entered into my router settings for web interfaces to bittorrent etc, but of course these have a good chance of being invalidated at each DHCP refresh cycle.

How will it work? I will need to forward port 443 to the 10.10.0.55 interface right? Without doing that, there is no way this is going to work... is there? And that means that I can't run more than 1 ip-based SSL virtual host on one machine because I can't forward 443 to two different interfaces.
Also, do I use internal ip address or external ip address in the <VirtualHost > tag? I only have one static public ip.
Can we enable IP tables to forward multicast or broadcast messages?
