Hey,
I have a problem. I try since yesterday to set Gitlab with an external SMTP server but whenever I do anything on the web with emails is a 500 error. Here is my current smtp configuration

`### GitLab email server settings
###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
###! Use smtp instead of sendmail/postfix.

gitlab_rails[‘smtp_enable’] = true
gitlab_rails[‘smtp_address’] = “cmail01.mc-host24.de”
gitlab_rails[‘smtp_port’] = 25
gitlab_rails[‘smtp_user_name’] = “noreply@serversucht.net”
gitlab_rails[‘smtp_password’] = “<my_passwort>”
gitlab_rails[‘smtp_domain’] = “cmail01.mc-host24.de”
gitlab_rails[‘smtp_authentication’] = “login”
gitlab_rails[‘smtp_enable_starttls_auto’] = false
gitlab_rails[‘smtp_tls’] = true
gitlab_rails[‘smtp_openssl_verify_mode’] = ‘peer’

If your SMTP server does not like the default ‘From: gitlab@localhost’ you

can change the ‘From’ with this setting.

gitlab_rails[‘gitlab_email_from’] = ‘noreply@serversucht.net’

###! Can be: ‘none’, ‘peer’, ‘client_once’, 'fail_if_no_peer_cert’
###! Docs: http://api.rubyonrails.org/classes/ActionMailer/Base.html

gitlab_rails[‘smtp_openssl_verify_mode’] = ‘none’

gitlab_rails[‘smtp_ca_path’] = “/etc/ssl/certs”

gitlab_rails[‘smtp_ca_file’] = “/etc/ssl/certs/ca-certificates.crt”
