[Exim] Outlook 4.xx and AUTH

Hello

I see that Outlook 4 don't work with standard AUTH.
EHLO command in normal situation replay something like this...

EHLO dns
250-reserva Hello localhost [127.0.0.1]
250-SIZE 13631488
250-8BITMIME
250-EXPN
250-PIPELINING
250-AUTH LOGIN
250 HELP

but Outlook 4.x don't understand this and don't authoritate on the server.

I have sawn that a MS Mail server replay this

EHLO dns
250-cas says hello
250-SIZE 0
250-8BITMIME
250-DSN
250-AUTH=LOGIN NTLM
250-ETRN
250 EXPN

AUTH= ?

This is the problem.

With these patches, I have added a new boolean option "auth_hack_outlook4".
If this option is set to true, exim duplicate AUTH in the EHLO reply and
Outlook 4 can work with exim AUTH.

EHLO dns
250-reserva Hello localhost [127.0.0.1]
250-SIZE 13631488
250-8BITMIME
250-EXPN
250-PIPELINING
250-AUTH=LOGIN
250-AUTH LOGIN
250 HELP

I have see that Outlook need too this prompt in AUTH LOGIN EXACTLY

server_prompts = "Username::: Password::"

I hope it will be usefull for more people
