validate email address with Python

Question

I'm trying to validate emails using validate_email 1.3 : Python Package Index, like this:

from validate_email import validate_email
is_valid = validate_email('[email protected]',check_mx=True)

How can I speed this up? My for loop isn't very effective with amount of emails I need to verify...

I think speeding this up is rather impossible since check_mx checks every SMTP-server by trying to establish a connection to it wich takes some time. However, since this is a so called I/O-bound process you can try to use different threads in parallel. — albert

Do you just want to validate that the string looks like a proper email address, or do you need to verify that the email account actually exists? — John Gordon

I need to verify MX record as well, I'm thinking of "multithreading" ... — alexus

Only use check_mx=True the first time you encounter a domain. After that, just use a regex to validate the address.

I'm not sure what you mean.

If I to use verify=False in addition to check_mx=True, your solution wouldn't work.
