Quote: Attackers are constantly changing their tactics and adapting to what the security community and researchers are doing, and it's not unusual for the bad guys to adopt techniques used by their adversaries. The latest example of this is a malware gang that has deployed what amounts to a honeypot designed to monitor the activity of researchers or other attackers who try to access a command-and-control server.
View 1 Replies View RelatedBot herders and the crimeware gangs behind banker Trojans have had a lot of success in the last few years with using bulletproof hosting providers as their main base of operations. But more and more, they're finding that social networks such as Twitter and Facebook are offering even more fertile and convenient grounds for controlling their malicious creations.New research from RSA shows that the gangs behind some of the targeted banker Trojans that are such a huge problem in some countries, especially Brazil and other South American nations, are moving quietly and quickly to using social networks as the command-and-control mechanisms for their malware. The company's anti-fraud researchers recently stumbled upon one such attack in progress and watched as it unfolded.

How do I make a local mail server that itself is a client to a WAN mail server.I want the local mail server to query new mail every 30 minutes from the WAN server.
View 6 Replies View RelatedCan this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

I have set up postfix and dovecot as per the Ubuntu anual and appear to have a functioning mail server.Using the sendmail command I can send mail and I receive mail in ~/Maildir. Using Thunderbird I can read any mails received but I can't send any mail from Thunderbird. I have tried with both STARTTLS and SSL/TLS and whilst I get the prompt for a password I keep getting the message my password for my server is wrong.I have ports 25, 465, 587 and 993. Is that all the right ports?When I ping my domain name it resolves to my router name whereas I believe it should resolve to my IP. Could there be a problem with my host file? I've had a play but to no avail.Here's the error in mail.log.

Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.
A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.
A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:
ISP supplied CISCO router
Draytek VigorPro 5510 UTM
Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:
CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server
I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...
I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?

I have to administer a few mail servers, a mail log server, 4 nameservers and a web server -all running on Centos 5 server distributions. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and mail log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves. I have already installed VMWare Server 2.0 I have a few questions:
- How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program?
- How do I actually do this cloning? Is there a tutorial on how to do this?

I have a Fedora 10 machine that I want to setup to send email. However I don't want it to be a full blown SMTP setup.What I am looking to achieve is when something sends email from the local machine (e.g. from cron) to an address I want it to use an MTA on the local machine which will then connect to, and authenticate with, my e-mail providers SMTP server this will then take care of actually sending the e-mail.I don't want, or need, to setup a full blown SMTP service (i.e. only the local machine should be able to use it) so sendmail seems a bit over the top for my needs. Nor do I want to mess about with MX records (am I right in thinking this will mean I have to manage all mail for my domain?).
View 2 Replies View Relatedi basically had this system installed for our mail system.The setup is as follows:
1. Operating system installed is Debian ver. 5.0.3
2. Roundcube is installed as a webmail(if its right for me to say that)
3. The server is hosted right here at our offices
4.The server uses relay system to send mail i.e. relays all our mails to our ISP
That all i can say about the configurations becuase thats as much as i understand it.The problem now is that we are not able to send or recieve emails from both internal and external.I tried to send mail to a collegue in the office who is on our local LAN,Roundcube says sent successfully but the person does not recieve the mail.i tried to send to my yahoo address but nothing.I dont know where these mails have been trapped.

View 6 Replies View RelatedI was using an email server from Icewarp, Merak Mail server V8.0.3 with a keygen for total full free use... I liked this server package... as everything is in there I need and it is controllable from a single window. Now I am planning to move to Linux... They have a Linux version, but not stable and expensive. Is there any thing almost free/less expensive (Specially they need yearly payment for upgrade of even the anti virus and anti spam)?
I need a almost same thing (except of the ftp and VoIP) like Merak (because that I really liked for ease of administration) in Linux? Like a Qmail with real strong Anti Virus and Anti Spam, with unlimited domain and user+autoresponder, mailing list, etc all but controllable from one single GUI?
