GitLab SMTP Server settings

Hi I am new in this Forum, cause I have one Porblem.
My Problem is the SMTP Server-configuration.
Here: https://docs.gitlab.com/omnibus/settings/smtp.html#sendgrid-with-api-key-authentication

on this Site I have make it like the example for Sendgrid and when I want to verify ma E-Mail-address, no E-Mail comes in my Inbox. And now the question what I’ve made wrong?

here my Configuration:

gitlab_rails[‘smtp_enable’] = true
gitlab_rails[‘smtp_address’] = “smtp.sendgrid.net
gitlab_rails[‘smtp_port’] = 587
gitlab_rails[‘smtp_user_name’] = “apikey”
gitlab_rails[‘smtp_password’] = “###MyKey123###”
gitlab_rails[‘smtp_domain’] = “smtp.sendgrid.net
gitlab_rails[‘smtp_authentication’] = “plain”
gitlab_rails[‘smtp_enable_starttls_auto’] = true
gitlab_rails[‘smtp_tls’] = false

I use the newest Version of Gitlab-ee.
(when someone need more Details, please write it)

I am also facing the same issue. If you are able to fix the issue

Please let me know resolution

Probably late, but you should also set your from field:

gitlab_rails[‘gitlab_email_from’] = ‘sendergrid@youtdomain.com’
