I'm new to Asterisk.

Basically all I need to do is set up Asterisk to have dynamic extension numbers based on Active Directory (LDAP) SID. AKAIK the SID is always the same prefix, followed by unique numeric user ID eg. 1-2-3456789-ABCD-EF123456789-123456

I'd like to use such number for the extension creation.

Basically the user will log in and Asterisk will give him the extension number same as the suffix ID, so that there could be dynamic tracking of call centre member performance.

Is that possible?

I'm being attacked from a botnet and I found out about it because I got this email from mailer-daemon telling me there's no space left on device. The mail.log was filled up with messages like

Dec 5 01:56:14 ip-xxx-xxx-xxx postfix/smtpd[9634]: NOQUEUE: reject: RCPT from xxx-xxx-xxx-xxx.dynamic.hinet.net[xxx.xxx.xxx.xxx]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<xxx.xxx.xxx.xxx>

I wrote a botnet killer script. The script uses iptables to ban NETWORK RANGES with too many IP ADDRESSES trying to send messages through my server, producing the above messages in logfile.

I'm sure this can kill a legitimate traffic. I decided I need this traffic to be as follows:

S0 - standard traffic - <1 mail per minute
S1 - increased traffic - 1+ mail per minute
S2 - suspicious traffic - 10+ mails per minute
S3 - potentially unwanted traffic - 1+ mails per second
S4 - attack - 5+ mails per second

...treated as follows:

S0: No action
S1: Log
S2: Log&MailReport (to postmaster@localhost)
S3: Log&MailReport&AutoBounce (solve capcha at http://myhost.tld/anti-spam )
S4: Log&MailReport&AutoBounce (you were temporarily blocked by the mailserver)
S5: Log&MailReport&AutoBounce&AutoAbuseReport (User [email protected] is abusing our server)

Is there any way to accomplish this using postfix? If not - is there any better mailserver for that?

Thank you

EDIT: I've completely rewritten this question because people got confused and thought it was an open relay

I have a really simple question but the answer may be a little more complex I guess.

Okay. Let's go. I have an Application called Xsplit Broadcaster (http://www.xsplit.com/). It supports streaming video through RTMP. Now what I want to do is this:

                                              +--(720p)--> TwitchTV FirstChannel
XSplit --(720p RTMP)-->[MyTranscodingServer]--+
                                              +--(360p)--> TwitchTV SecondChannel

Is there a simple way to do this?

Additional info: Both channels accept standard RTMP stream on their RTMP endpoint using either username/password or streamkey. The server operating system is GNU/Linux. The solution may not be paid, otherwise we'd be using AkamaiHD Network or such service. This is a non-profit project.
