(Migrated from github.com)

Just found out through this trending repo on HN that recipient validation via SMTP is possible – and that this beautiful library exists. 🤯

Library looks very promising, however I have issues installing it under macOS Big Sur – certificate validation fails when pulling the blacklist. Tried on both local internet and mobile hotspot – never saw a side-load during installation routine though, heh.
Installing works flawlessly on Ubuntu.

Probably similar to https://github.com/karolyi/py3-validate-email/issues/67

I have read and understood the FAQ

PS: Anything that needs contributing?

edit: Did some digging and this might explain the issue.

Can be fixed running the following – and then obv. adding the exports to .bash_profile for the future:

pip3 install certifi
CERT_PATH=$(python -m certifi)
export SSL_CERT_FILE=${CERT_PATH}
export REQUESTS_CA_BUNDLE=${CERT_PATH}
