What is the default email server for Teamcity 7.1?

Question

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?

Answer 1

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.
