1. Proposed title of this feature request

    [RFE] - Include sasl-xoauth2 as a package in RHEL

2. Who is the customer behind the request?

    Proactive RFE.  See non-exhaustive list cases linked to [KCS - Basic Authentication will be turned off in Exchange Online.](https://access.redhat.com/solutions/6981478).  

3. What is the nature and description of the request?

    From [Microsoft - Exchange Online to retire Basic auth for Client Submission (SMTP AUTH)](https://techcommunity.microsoft.com/t5/exchange-team-blog/exchange-online-to-retire-basic-auth-for-client-submission-smtp/ba-p/4114750)

    > Today, we are announcing that Exchange Online will permanently remove support for Basic authentication with Client Submission (SMTP AUTH) in September 2025. 

    From [Red Hat Bugzilla – Bug 2134519 - Juan Manuel Santos](https://bugzilla.redhat.com/show_bug.cgi?id=2134519) emphasis added

    > Adding it to EPEL would be a huge leap forward, as we would at least have something for customers that is more or less official/tested, even if not fully supported. *Plus, we would be in a good spot if Microsoft/Google suddenly decided to no longer offer support for basic authentication.* I guess once it's in EPEL we can review the SELinux side of things to find out whether it can be added to selinux-policy-targeted or in a separate, Postfix-related package.

    From [Bug 2134516 - [RFE] Add cyrus-sasl-xoauth2 as a package (edit)](https://bugzilla.redhat.com/show_bug.cgi?id=2134516)

    > This was done some time ago. We did sasl-xoauth2 package though as we got reports that this is working better for our customers:
    > https://github.com/tarickb/sasl-xoauth2
    > The package is no awailable in Fedora and EPEL8/9:
    > https://src.fedoraproject.org/rpms/sasl-xoauth2
    > Closing as done.
