Unblock domain spamgourmet.com to register GitLab.com accounts
Problem Statement
Customers that have their email in the free email service domain "spamgourmet.com", can start register an account at Gitlab but they will never receive the confirmation email and/or password reset email so, they will create an unusable Gitlab account.
Reach
Any new customer of GitLab.com that uses the free email service domain "spamgourmet.com".
1.5 = Small reach (~5% to ~25%)
This is just a guess of the amount of customers that have an "spamgourmet.com" email account and they can not use it for Gilab.
Impact
Any new customer that face this issue is probable that go to https://github.com/ instead of using Gitlab.com
0.5 = Low impact
Confidence
This is an active issue. You can find all the details at the GitLab Support ticket: 157728
100% = High confidence
Effort
I am pretty confident that the SMTP validator is a regex that excludes this domain to be send the emails so, in order to fix it, I guess that an engineer will spend 30 min. (or less to) fix it.
