Could be coming from bounces It seems. It seems these bastards are sending out using fake email address. gamera is sending back failure notice and the sistems fails under hundreds email. As i know there's no way to prevent gamera sending out failure notice, correct? I suppose it is a common problem.

Looking into /var/log/qmail/current i see qmail is sending out mail to some server for sure we never send to.

How is it possible ?
It seems gamera is acting like a sender mail even if it should send only to servers listed in /var/qmail/control/smtproutes

other than 25 on gamera system; is it possible? How?

In my case it is not a permission problem. I had to reinstall the server...i did it twice in 15 days. It is a very strange situation i can't understand. nmap was reporting port 25 as 'filtered' but it wasn't. To have gamara working again i had to completly remove iptables. After that for one day por...

again, after one week installation, the system is out. it seems i can't receive any email. The logs are reporting any activity. I've few connections: # netstat -n |grep -c 25 35 I tried restarting more than one time. smtp is active on port 25 but telnet on port doesn't respond. nmap reports port 25 ...

how big is the queue? was growing fast, 50 email per minute and were not 'failures' (not only). Problem was that At the moment the situation is quite fine, just 60 and all of them failure notices. But give me your opinion. Email are delivered with delay. During the day also 4 hours. Now the server ...

try running init q, or rebooting and then test port 25 there must be a but on centos-4x x64. I reinstalled it on a centos-5 32 bits and gamera starts. Now my problem is that queue grows a log and emails aren't delivered. I am lost. dns is working, from the server i can ping the world. What i see is...

I follewed the easy steps here: http://www.atomicrocketturtle.com/Joomla/content/view/77/2/ after reboot i've spamassassin, clamav running but no email are delivered. This is my log: # tail -f /var/log/maillog Sep 14 02:06:36 spamd[3651]: server successfully spawned child process, pid 9104 Sep 14 02...

Yes, it must be a firewall related issue.

Thanks

i already tried to 'clean', i also tried to recreate a new /var/cache/yum directory ... but the same error.

Not really, you can try and drop the traffic with firewall rules, although if its a syn flood I suspect they're probably spoofing the src ip. Yes Scott, it was syn flood. I took all the suggested action to prevent it working on tcp/firewall. It was the first time i had this kind of attack on a anti...

My gamera server seems to be under ddos syn attack. maillog file don't help becaasue i've so many connections it can't process a bit. i know it should be solved firewall side but maybe there something i can look into the gamera server to understand which webiste (if any) is under the attack ?
