Yes, but not enough. Our university decided to set up a third party 
authenticator called OKTA so these things need to talk to each other.

We have figured out how to do this talking and can download e-mail writing our 
python code but it comes down in json format. I don't want to have to write an 
entire MTA or e-mail client just to read my e-mail. So I was looking at some 
other option that can be used.

I came across something called JMAP but I am not sure if it is relevant. All 
this is a bit beyond our domain of expertise and that presents a problem.

fetchmail 7 alpha has support for this but it is specific for gmail (which is 
your use case). I have built an RPM for this and am running it, but I have 
noticed that the copr site also has a new RPM here:

https://copr.fedorainfracloud.org/coprs/vcrhonek/fetchmail-7.0.0-alpha/

I know that my RPM works and retrieves e-mail from other servers that do not 
use this 2FA drivel. I am sure that the copr one does too, but i have not tried 
it. Btw, fetchmail's options on ssl has changed (you need sslmode wrapped) in 7 
alpha.

It is not enough to run fetchmail. You need some python code to get your token 
which is here:

http://mmogilvi.users.sourceforge.net/software/oauthbearer.html

Note also that you will need to figure out a way to send mail via postfix or 
some other option. That webpage is pretty detailed.

Best option is to ignore OAUTH2 for as long as you can.

As I said, this is not relevant to my case.

HTH,
Best wishes,
Ranjan

I can't for the life of me tell: Is Office 365
"multifactor authentication" the same as OAUTH2?

I've been trying to find a fetchmail-like thing
that supports OAUTH2 so google will stop badgering
me about using an insecure access, and there is a
python thing called "getmail" which, in theory, has
a plugin for doing OAUTH2 access.

I haven't tried to set it up yet, so I don't
know if it works to make gmail happy or not.
(I keep seeing references to fetchmail 7 having
support for it, but I can't find any pointers to
even a beta of fetchmail 7).

Thanks! Unfortunately, this is not an option for me. There is no forwarding 
allowed, and I am in academia where (unless you are an administrator, in which 
case you get to set policies for others to suffer) you are expected to receive 
and answer e-mail all the time.

I will wait to see if there are some other pointers on how to get MS Graph to 
integrate with a linux MTA.

My solution was a lot simpler when I wanted to read work emails in my
linux client.  I just turned on forwarding in Office 365 to an email
address on my server at home.  I spoof the "Reply To:" back to my work
address, though I almost only *read* emails from home. I rarely reply
until I get to work the next time.  My office doesn't use two-factor
authentication, so I don't know if that makes this impossible...

It's not perfect, but it only took 30 seconds, and it's good enough.

OT: using MS Graph to retrieve e-mail from Office 365 and deliver to linux MTA on F29

2019-03-20 Thread Ranjan Maitra
Dear friends,

Our workplace recently switched to OTP-based two factor authentication with 
Office 365 and mandated everyone to use the browser, Windoze or Evolution. We 
want to do none but get e-mail the old-fashioned way, delivered to my local HDD 
and read by my mailer. Looking around, we have successfully written python code 
to get e-mail using MS Graph. But following the examples there, we can retrieve 
e-mail in json format and needs further processing before it can go to a MTA. I 
am not sure that procmail will work, so I am wondering how to deliver mail to 
my HDD in Mbox format (to be read by sylpheed or some other e-mailer).

But, is json format the only way to extract these e-mails? Or are there other 
options available that are friendlier for more general MTAs? Otherwise, how 
does one get these e-mails in a Mbox format?

Sorry if my question is not very clear: we are very new to this and still 
struggling to understand everything.

Many thanks for any helpful pointers and references, and best wishes,
Ranjan
