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?

email::sender::transport::smtp

Email::Sender::Transport::SMTP(3pm)			User Contributed Perl Documentation		       Email::Sender::Transport::SMTP(3pm)

NAME

       Email::Sender::Transport::SMTP - send email over SMTP

VERSION

       version 0.110005

DESCRIPTION

       This transport is used to send email over SMTP, either with or without secure sockets (SSL).  It is one of the most complex transports
       available, capable of partial success.

       For a potentially more efficient version of this transport, see Email::Sender::Transport::SMTP::Persistent.

ATTRIBUTES

       The following attributes may be passed to the constructor:

       "host": the name of the host to connect to; defaults to "localhost"
       "ssl": if true, connect via SSL; defaults to false
       "port": port to connect to; defaults to 25 for non-SSL, 465 for SSL
       "timeout": maximum time in secs to wait for server; default is 120
       "sasl_username": the username to use for auth; optional
       "sasl_password": the password to use for auth; required if "username" is provided
       "allow_partial_success": if true, will send data even if some recipients were rejected; defaults to false
       "helo": what to say when saying HELO; no default
       "localaddr": local address from which to connect
       "localport": local port from which to connect

PARTIAL SUCCESS

       If "allow_partial_success" was set when creating the transport, the transport may return Email::Sender::Success::Partial objects.  Consult
       that module's documentation.
