I don't know what to do, I know how to block and delete pretty much every other type of abuse. I run a server with 500+ shared hosting clients and reseller clients and it was just blocked because of email spam. I can keep on top of all other abuse (people trying to do dos attacks etc) but the one thing I can't get my head around is email spamming. how to stop people spamming emails from my server?

Problem: My Email Address is spamming Situation Chronology: 1. I received an email (spam) on Yahoo Mail from someone who was not intending to send it. (While it did go to spam folder, I did 'open' the email (since it came from a trusted sender) but it only contained a link (which because of WOT) I assumed was spam.) I did NOT click the link. 2. I then informed him that his email addy was spamming.3 Shortly thereafter, i noticed in Ubuntu (firefox) whenever I clicked "reply" to email back to someone, there was a quick flash of letters/numbers in the slot where I would normally write. This instantly disappears and goes blank so I can write something, so I just figured it was a bug.

So far: I have 1. Changed my Yahoo password 2. Deleted firefox 3. In windows Ran Spybot/Search-Destory AVG (turns up nothing) What else can I do?
I run my own home server using OpenSuse 11.1, everything is setup using apache, php, etc etc, and it all works perfect, but now I need to use my own email server for the use of Dolphin social networking software, so that when someone registers, the email server sends out registration confirmation emails, so I set up postfix, yeah right!!!, even though I followed all instructions to set postfix as a closed relay, a test done at mxtoolbox site still said it was an open relay, but while I was trying to set up postfix, my access to the server slowed down, and my servers drive light was constantly active,,, so when I look at the mail queue, I saw 4000+ emails, all from japan, (hinen.net), so I promptly shut down postfix and use postsuper -d ALL in the command console to delete the queue, but no matter how I try, I couldn't configure postfix as a closed relay,,, so I uninstalled it and installed sendmail, and using webmin, I could use a spam list and block the domain, now, sendmail's test at mxtools show as a closed relay, I can't even send out a test email using smtp auth, but disabling auth, I can, but now my IP is blocked at spam cop, and spamhaus,,, gmail server say my IP is not authorized to send to their servers, but to use my ISP relay instead,,, but my ISP doesn't have a relay,,hence the need to run my own email server.
My home server uses double layer firewall, a hardware firewall between the internet and the server, and a software firewall on the server, and I only allow the ports I need, IE, 80 = http, 443 = https, 20/21 = ftp, 25 = smtp, 110 = pop3. and that's all, but any other internal access from my workstation to the server, using ssh, I only open the ports on the server firewall. If someone here has a great deal of knowledge on sendmail, and can set up a an M4 (linux.mc) config file for me, it would be much appreciated. What I would like my email server to do, is to only allow the sending of emails from inside it's own server system,, ie, when a php script sends an email to the server, then the email server would let it through, but anything else, outside the local network is ignored.

View 2 Replies View Relatedcan we block email address in a way that a user cannot login into multiple systems simultaneously, so that if a user logs in into a system (with ip address 192.168.1.22)and if he tries to login to into another system at the same time(with ip address 10.0.0.5) his previous system(i.e 192.168.1.22) has to logout automatically. Is there any predefined scripts for this.

Have someone used Linux heartbeat to send email when the Slave server becomes the Master? I've read I can configure the MailTo under.
But I really don't know how to do it. I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node.
I manage a linux-based network, where some projects are currently under development. Our IT policy states that any email attachment shall be encrypted using GPG. Can I block other attachments using a firewall?
Note: Currently our mail server is not in campus. So I can only use a firewall for this security issue.
The problem I have is so simple yet difficult for me to resolve. My Postfix MTA allow fake mails from me@example.com to me@example.com. How can I block them?
For example, if I do "telnet smtp.mail.yahoo.it 25", as I write the MAIL FROM command I get the alert "Authentication required". How can I achieve that?
