Hi Odhiambo.
The AUTH is incorrectly advertised. A correct setup would announce all the mechanisms available for authentication.
So, a correct answer at smtp will be, for example:
250-AUTH PLAIN LOGIN
And what the office 365 servers are answering is:
250-AUTH
This is incorrect and that is the point of the problem because exim search for the correct credential when acting as a client, based on the mechanisms available (and in this case, there are no one mechanism available because no one mechanism was announced).
This is what I search and asked if someone else has or had the same problem because I think that the two ways to fix this is:
1 - make the office 365 do the right answer when receive the EHLO verb (but it's exchange and it's microsoft - what means that this probably will never be fixed).
2 - make the exim do the authentication using some fallback-style-schema when you already had setup hosts_require_auth for some of the office 365 servers).
Had any other idea?
Thank's
And... Ya... It's friday... My brain is exhausted too!

How can you use AUTH when it's not advertised? Or maybe it's Friday my brain is already tuned to something.

Hi all.
I had a situation today where i need that exim act as client on office365 server with authentication.
So, i have configured two authenticators (one for PLAIN and other for LOGIN) that will be sent after TLS.
The problem that i found is that the office365 server isn't doing the correct announce of AUTH mechanisms....
Running exim in debug mode i saw this:
SMTP<< 250-pod51028.outlook.com Hello [189.74.52.32] 250-SIZE 36700160 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-AUTH 250-8BITMIME 250-BINARYMIME 250 CHUNKING
They are announcing only that has auth capability, right? So... the exim don't find the correct authenticator data to use:
207.46.4.237 in hosts_require_auth? yes (matched "pod51028.outlook.com")scanning authentication mechanismsskipping server_plain authenticator: not configured as a clientskipping server_login authenticator: not configured as a client SMTP>> QUIT
So... My doubt is... There are a way to configure exim to use for example LOGIN mechanism as fallback when it don't find any valid mechanism for auth as client? Someone had the same problem? How to fix this? Or maybe this is something to send to bug list?
Thanks
