Hey,

Sorry to hear you are having problems with mailscout.

When I check the code on my own Colab, I face no issues. As expected, it returns an empty list (as Batuhan Akyazı does not have a microsoft.com account), however, it checks the emails successfully. I can also get a full list with legit domain + name combinations.

Since I can't replicate the issue, I can only guess the reason behind it.

One reason might be that the Colab instance you use has been IP-banned by the mail server. Using a different instance may help in this case (by simply using the Disconnect and Delete Runtime button). Mailscout is also prone to getting your IP banned if used in high concurrency (simply because it means spamming the server), but I believe that's not your case.

I would also suspect the port 25 on the instance you use. But I suppose it would give you a specific error if that was your case. I use Colab Pro so my instances may allow me to use the mentioned port, while Colab Free may block it by default.

Again, these are just my assumptions as I am unable to replicate the issue.

If you have found more evidence to elaborate on, I would be more than welcome to provide further support :)
