View 1 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.

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?
View 7 Replies View RelatedI 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 6 Replies View RelatedHave 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 have recently setup a new mail server and have simulated sending and receiving on the new email server. The new email server will replace the primary one.I would like to setup the new email server in parallel with the existing one.This way i can observe issues that might occur and be aware of what could go wrong. I want to received mail to be delivered to both mail servers at the same time.I would like to use postfix, exim i find a bit to difficult to understand.I have thought of using transport maps, the only problem is that you can only forward mail to one server at a time using transport maps.I think recipient_bcc_maps and sender_bcc_maps could work, i would just like ideas of how i can do this.

View 7 Replies View RelatedWe use procmail to reformat and filter email messages sent from many lead capture websites where the clients enter their reply email address manually.When we receive the message at our application we send a welcome email, and receive back the Undeliverable Email message where the clients entries are invalid, but I would like to be able to kill messages with undeliverable email addresses on our mail server before they are delivered to our application.I have found discussions on filtering masqueraded addresses, but since the IP of the sending system is not related to the entered client's email address, this does not appear to help. I would think that it should be able to query the email server to identify if the address is valid.

I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.
