XI Receiver MailAdapter

Question

Help needed:  I have problems to set up a connection  from XI  to  MailServer, in order to send a mail   (RECEIVER MailAdapter)
XI:System:    NetWeaver 7.0
MailSystem:   MS Exchange 2007
Problem is, that MS Exchange  requires   TLS   (but NOT  SSL ).
I have read many Blogs/Threads, but have not found yet, whether it is in principle possible to set up this  TLS (instead of SSL)
I tried with    Server:      smtp://host    and    smtps://host     - both failed
The connection to the server failes in both cases with:
a)  server does not support PLAIN or LOGIN authentication     (SSL off):   smtp://host  )
b)  unable to create a socket                                                 (SSL on:   smtps://host )
Any idea  out there ?
(switch to SSL or None  on MS Excange is denied by our Mail-Admin ,  aslo  IMAP will not be supported for outgoing mails)
Bye the way:    SENDER Mail Adapter via  IMAP   works !

Thanks for reply and the link.
But unfortunately this does not help.
There is no problem to set up / configure  all the Interfaces, Mappings, Communication channels at all.
The matter is, that I don't know how to set up the connection  with   TSL encryption (instead of  SSL  or  None)  in the CommunicationChannel itself.    I don't believe that this can be handled inside the payload  or mail-content.
One idea may be, that in the MailAdapter itself the  TSL  must be implemented (by SAP ? ) or can I do this on my own ?
