Jun 30, 2011I have configured qmail on my CentOS5.5 server. I am planning to divert all the mails sent to one domain to be diverted to another domain.

View 5 Replies View RelatedUbuntu Servers :: Redirect All Outgoing Emails?
May 10, 2010Here's what I'm trying to do to complete my rocking development server.
I would like all outgoing email on my Ubuntu server to be redirected to one email address (internal or external). I don't have any mail server installed yet (I'll probably use postfix unless you have another suggestion).
The reason I would like this to work is because I'm a web developer working on multiple projects. When I start working on a new project I would like to be able to test some of the forms and features in the web application (PHP) without having emails sent to the email address configured in the application. I can always change configurations but having my development server forward the emails would save me lots of trouble.
Example:
If one of my php application sends an email to: user1@domain.com, user3@domain4.com... I would like all of them to forward to myemail@domain.com

View 5 Replies View RelatedUbuntu Servers :: Outgoing Mail ALWAYS Flagged As Spam
Mar 2, 2010I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.

View 9 Replies View RelatedUbuntu Servers :: Server Can't Make Outgoing Connections
Jul 17, 2011I have a ubuntu 10.04 dedicated server that I am having problems with. It intermittently cannot connect to any other servers outside its network.
Code:
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
^C
--- 8.8.8.8 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7008ms
(I have tried a bunch of other ips too and none outside its network are pingable) I'm not sure if this is a problem with my server or a problem with the networking outside the server. I have been emailing my server provider and they keep on insisting the problem is with the server and that their network is working fine. Apparently all of their other servers work and they can login into the gateway and ping 8.8.8.8 from there. So they just want to reinstall the OS, but I thought I'd post here to see if anyone has any ideas.
Here is some info I have gained while troubleshooting: I haven't changed any settings at all on the server for months. I haven't done any updates for about a week. The strangest thing is that this is intermittent, there have been a few times in the last 24 hours where I have been able to ping 8.8.8.8 or other ips, but 98% of the time I can't. I have also tried rebooting the server, which had no effect. I can ping the gateway, and I can ping other servers on the same subnet. I can ssh onto the server from my home internet connection, and I can view webpages on apache, so incoming connections work.
Networking :: Using A Different OUTGOING IP ADDRESS
Jun 23, 2010I am testing my setup which will have 2 public servers. HTTP & MAIL both with reverse DNS established.
www.mydomain.no -> xxx.xxx.xxx.034 -> internal name server
mail.mydomain.no -> xxx.xxx.xxx.035 -> internal name mail
Both addresses are on the same NIC with 34 being the main address.
The system work fine except one thing. The IP address mail sends out from is the Firewall Address _FW. I can see why as the default gateway set on the mail server is the FW_IP (The main gateway ip)How can I get the MAIL server to send through it's own public IP.I understand I can change the Firewall public IP to that of the Mail server and that would cure the problem for now. If it's possible I would like to learn a little in the process.
Ubuntu Networking :: Unusual High Outgoing Traffic Generated
Aug 12, 2010I've noticed recently that a lot of outgoing internet traffic is generated by my laptop (running Ubuntu 10.04 - 64 bit). This wasn't the case previously. I only found out because my wireless broadband traffic allowance suddenly was used up very quickly. I've installed ntop to try to find out where all this traffic is going to.
I did find that there were a very high number (at one stage over 11.000) of active TCP/UDP sessions (see attached screenshot). Although the traffic generated by each is only small (about 100 bits/bytes - not sure what) multiplied by thousands, makes a fair bit of traffic. I wonder if I've got some kind of a virus/bug or do I have a configuration problem with my laptop?
Ubuntu Networking :: Iptables: Block Incoming And Allow Outgoing Traffic
Jan 6, 2011I need to configure iptables to block incoming traffic (except specific ports), but allows all outgoing traffic.
I am able to block incoming traffic, but doing so also prevents outgoing traffic (tested by telnet [URL] 80)
The following was used:
iptables -A INPUT -p tcp --dport ssh -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -I INPUT 1 -i lo -j ACCEPT
iptables -A INPUT -j DROP
Also, even allowing NOT SYN requests still prevents outgoing traffic.
iptables -I INPUT 1 -p tcp ! --syn -j ACCEPT
Another point:
# modinfo ipt_state
modinfo: could not open /lib/modules/2.6.18-028stab070.14/modules.dep
How to install ipt_state module on ubuntu?

View 3 Replies View RelatedNetworking :: Capture Outgoing Packets Only?
Jun 11, 2009I have a network like
Node A to Vlan Switch
Node B to Vlan Switch
Node C to Vlan Switch
Node B is set up to be a middle man between A and C.
All nodes have 1 NIC.
They are all linux boxes. Node B can ping Node C. When I try to ping Node C from Node A, the ping just hangs forever.
When I use Wireshark to sniff What's going on with Node B during a ping from Node A to Node C, I can see an ICMP request with src = Node A and dest = Node C. I'd like to know if that ICMP packet was received by B from A or if it is going out. If it's going out, that makes no sense since B knows how to send to C. If B is only getting the requests but not forwarding them, then I know there is something wrong with B's configuration.
So I'd like to be able to sniff incoming packets only, or outgoing packets only. Is there a way to do this?
