Bug with login page on support site

Hi

I have been trying to open a support request however it is just not working, Your support site is not sending any email for verification.

I have tried gmail, yahoo and and many other email accounts , just in case if it works however it looks there is an issue with SMTP on your WordPress and it is not sending any email for account registration and we are unable to file any support ticket

Please help and fix this
