Email Authentication schemes available in Oracle XML Publisher

Hi,

We are using Oracle E-Business Suite 12.1.3 with Oracle XML Publisher 5.6.3. We use XML Publisher Bursting to send out emails outside of our company. So far everything went good. Now, as part of Security Requirements Our Microsoft Exchange 2010 is going to be configured to allow only authenticated emails. Authentication schemes provided by the exchange are

       i. AUTH NTLM

       ii.  AUTH LOGIN after starting TLS (i.e., STARTTLS > AUTH LOGIN).

Now, will XMLP in EBS support any of the above authentication Schemes.?  or will it support only PLAIN authentication (i.e., AUTH PLAIN)?

Appreciate your response

Thanks,

Rafeek.
