@node Importing from ProtonMail with HKP for Python
@subsection Importing from ProtonMail with HKP for Python
Though this can provide certain benefits even when working with
ProtonMail, the scope is somewhat constrained there due to the
limitations of the ProtonMail keyserver.
For instance, searching the SKS keyserver pool for the term "gnupg"
produces hundreds of results from any time the word appears in any
part of a user ID. Performing the same search on the ProtonMail
keyserver returns zero results, even though there are at least two
test accounts which include it as part of the username.
The cause of this discrepancy is the deliberate configuration of that
server by ProtonMail to require an exact match of the full email
address of the ProtonMail user whose key is being requested.
Presumably this is intended to reduce breaches of privacy of their
users as an email address must already be known before a key for that
address can be obtained.

passed as a =homedir= which either does not exist or which is not a
directory, as also being a pssible user ID to check for. It's not
guaranteed to pick up on all such cases, but it should cover most of
them.
