SMTP and NTLM
Hi,

I have a HP Unix from which I'm trying to connect to an email server through telnet and test sending emails using commands. Why am I doing that is not important.
The email server is an Exchange server and it looks like that the only Authentication method it supports is NTLM.
The host name is "svrdb01".
Here is what I do:

telnet 172.19.120.36
ehlo 172.19.120.36
AUTH NTLM 4e544c4d535350000100000007220000060006002000000073767264623031

The hex number is made based on the following information:
- NTLMSSP Signature and Type 1 Indicator: (0x4e544c4d53535000 and 0x01000000)
- Flags: (0x07220000)
Negotiate Unicode (0x00000001)
Negotiate OEM (0x00000002)
Request Target (0x00000004)
Negotiate NTLM (0x00000200)
Negotiate Workstation Supplied (0x00002000)
- Supplied Domain Security Buffer (0x0600060020000000)
Length: 7 bytes (0x0700)
Allocated Space: 7 bytes (0x0700)
Offset: 32 bytes (0x20000000)
- Data section (workstation name "svrdb01"): 73767264623031

But in return I get the "Authentication unsuccessful" error. Am I doing something wrong? How can I make sure those flags I've set are actually correct? For example how do I know my OS actually supports NTLM?

mail::spamassassin::plugin::phishtag

Mail::SpamAssassin::Plugin::PhishTag(3) 		User Contributed Perl Documentation		   Mail::SpamAssassin::Plugin::PhishTag(3)

NAME

       PhishTag - SpamAssassin plugin for redirecting links in incoming emails.

SYNOPSIS

	loadplugin     Mail::SpamAssassin::Plugin::PhishTag

	trigger_ratio	 0.1
	trigger_target	 RULE_NAME  http://www.antiphishing.org/consumer_recs.html

DESCRIPTION

       PhishTag enables administrators to rewrite links in emails that trigger certain tests, preferably anti-phishing blacklist tests. The plugin
       will inhibit the blocking of a portion of the emails that trigger the test by SpamAssassin, and let them pass to the users' inbox after the
       rewrite. It is useful in providing training to email users about company policies and general email usage.

OPTIONS

       The following options can be set by modifying the configuration file.

       o   trigger_ratio percentage_value

	   Sets the probability in percentage that a positive test will trigger the email rewrite, e.g. 0.1 will rewrite on the average 1 in 1000
	   emails that match the trigger.

       o   trigger_target RULE_NAME http_url

	   The name of the test which would trigger the email rewrite; all the URLs will be replaced by http_url.

DOWNLOAD
