I encountered a mailloop between my gitlab-instance and my mailserver. Is there a possibility to prevent this? Is there something like a blacklist where gitlab will never send emails to?
The situation was like this: Gitlab has a dedicated emailadres: firstname.lastname@example.org which it checks for emails and sends mails from.
Somehow a loop got started where gitlab send an email from email@example.com to firstname.lastname@example.org. The mailserver then responded: “This emailadres does not exist”, to which gitlab responded: “I don’t understand your message”, to which the mailserver responded: “This emailaddress does not exist”, to which gitlab responded …
Is there a way to prevent this? For now, I restarted gitlab and emptied the mailbox email@example.com and modified the config-file to have the reply-to-adress changed from firstname.lastname@example.org to email@example.com.
