Move the SMTP_AUTH constants into a separate header file in
preparation for adding SASL based authentication to POP3 as the two
protocols will need to share them.
A dot character at the beginning of a line would not be escaped to a
double dot as required by RFC-2821, instead it would be deleted by the
mail server. Please see section 4.5.2 of the RFC for more information.
Note: This fix also simplifies the detection of repeated CRLF.CRLF
combinations, such as CRLF.CRLF.CRLF, a little rather than having to
advance the eob counter to 2.
Modified smtp_endofresp() to detect NTLM from the server specified list
of supported authentication mechanisms.
Modified smtp_authenticate() to start the sending of the NTLM data.
Added smtp_auth_ntlm_type1_message() which creates a NTLM type-1
message. This function is used by authenticate() to start the sending
of data and by smtp_state_auth_ntlm_resp() when the AUTH command
doesn't contain the type-1 message as part of the initial response.
This lack of initial response can happen if an OOM error occurs or the
type-1 message is longer than 504 characters. As the main AUTH command
is limited to 512 character the data has to be transmitted in two
parts; one containing the AUTH NTLM and the second containing the
type-1 message.
Added smtp_state_auth_ntlm_type2msg_resp() which handles the incoming
type-2 message and sends an outgoing type-3 message. This type-2
message is sent by the server in response to our type-1 message.
Modified smtp_state_auth_resp() to handle the response to: the AUTH
NTLM without the initial response and the type-2 response.
Modified smtp_disconnect() to cleanup the NTLM SSPI stack.
- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
- Use of true local host name (i.e.: via gethostname()) when available, as default argument to SMTP HELO/EHLO.
- Test case 804 for HELO fallback.
full DATA has been sent, and I modified the test SMTP server to also send
that response. As usual, the DONE operation that is made after a completed
transfer is still not doable in a non-blocking way so this waiting for 250
is unfortunately made blockingly.
in the same RCPT TO line, when they should be sent in separate single
commands. I updated test case 802 to verify this.
- I also fixed a bad use of my_setopt_str() of CURLOPT_MAIL_RCPT in the curl
tool which made it try to output it as string for the --libcurl feature
which could lead to crashes.
sequences in uploaded data. The test server doesn't "decode" escaped dot-lines
but instead test cases must be written to take them into account. Added test
case 803 to verify dot-escaping.
