OpenBSD imap LOGIN: NO madvise: function not implemented

[FozzeY]

Hydroxide is built from source as per the docs on OpenBSD 7.6.
Go version is go1.23.1 openbsd/amd64.
I am unable to authenticate with hydroxide imap using the correct bridge password. On both mutt and telnet I get a peculiar error on login:
NO madvise: function not implemented

Here are the debug logs from hydroxide imap:

To me it looks like the authentication process is successful, but in the end login is denied with the same error message.

Maybe an issue with boltdb?

boltdb/bolt#646

Seems like it, yes. Is there a workaround?

Maybe migrating to bbolt?
