Re: FreeBSD Port: mail/py-spf-engine py311-pyspf-2.0.14_3 cryptography issue

Thanks for you work on this and reporting it.

Does any of these issues match your case?

https://bugs.freebsd.org/bugzilla/buglist.cgi?component=Individual%20Port%28s%29&list_id=800076&product=Ports%20%26%20Packages&query_format=advanced&resolution=---&short_desc=mail%2Fpy-spf-engine&short_desc_type=allwordssubstr

I noticed that the port does not have a maintainer.

Personally I don't have time to dive into this, but I think it helps other committers if a Bugzilla issue exists with a clear patch attached.

Regards,
Ronald.
