is rumored to have said:
[...]
Would it be valid to presume that an SMTP server that can be connected
to,
securely, via Outlook, Thunderbird and the other common clients, can
be
connected to via the postfix SASL stuff?
No. There are authentication mechanisms supported by interactive clients
that are not supported by Cyrus. The most important ones are OAUTHBEARER
and XOAUTH2, which require an out-of-band (web) interaction following
the OAuth2 protocol, typically to support 2FA methods that require a
live human interaction.
Or is SASL/Cyrus an equine of
a different hue?
SASL is a broad framework used by many application protocols (SMTP,
IMAP, etc.) for authentication and each implementation is unique, but
hopefully they are interoperable when needed. As long as the relay isn't
requiring an authentication mechanism that is designed to exclude bots
(such as the those mentioned above) it should be possible to get Postfix
(using Cyrus) to authenticate to it.
