I have a dedicated server with a hosting company. Its CentOS 6.3/whm/cpanel. I am running 1 joomla site and 2 magento sites. Still in the early phase, not much traffic.
Everything is fine until recently i got system notification of /var 100% full.
It turns out my server sent tons of spam. I cleaned up /var/log, /var/lib/mysql/eximstats, changed some server security setting and exim settings. It's getting better. But
1. it still sending spam
2. it sending spam even with exim service stopped
3. my ip is in the blacklist of hotmail, yahoo etc.
I contacted hosting company, submitted ticket, called several times. Still not getting back to me about the solution. Should the hosting company warn me about the spam at the first hand. Then things not getting so bad as now.
What should i deal with this?
do i have to rebuild a server then do data migration?
Any other choice hosting company with better support? I am paying $120 for everything right now. My budget is less than $150.
Yes, something ( possibly one of your installed applications ) is compromised on your server which is lets the hacker to send spam emails out of your server. I cannot find a complete HOWTO that can help you to track the source. Perhaps you can read http://kb.iweb.com/entries/24423351-...er-cPanel-exim and try the commands.
To find which email header you should check, run exim -bp from commandline as root. That will display all emails in queue. From the result you can find a common pattern ( most probably the sender address ) and that can be the possible spammer. Take the email ID from one of such emails and check its header using exim -Mvh ( as mentioned in that article ). It may help. If you still cannot find the source, ask your hosts support or find a person who can help you.
I can help you identify the spam. It could be at times sendmail sending the spam. Even with exim we can easily trace with the exim header. I charge only less. Please contact me at [email protected] . AIM linuxworld2013
