Without any changes, email notifications stopped being sent from our continuous integration server which is a Teamcity 7.1 server. Up to now I’ve just used the default teamcity email configuration, which was this:
SMTP host: mail
SMTP port: 25
Send email messages from: Teamcity
SMTP login: <blank>
SMTP password: <blank>
Secure connection: none
Worked fine for last year or so. Now I’m trying to diagnose what is wrong, but I don’t really know what the above configuration is doing… Is it pointing to a built-in mail server that is bundled with Teamcity? Is it pointing to the company’s exchange server? Something else?
Teamcity does not have any bundled mail servers. This configuration point to your company’s SMTP server. By occasion, SMTP server’s name is ‘mail’. So TC tries to connect to mail:25 and send messages ‘from’ ‘Teamcity’
Please check if SMTP server’s authentication settings were modified (e.g., anonymous access is now forbidden). Also please check ‘teamcity-server.log’ for error messages related to sending notifications.
