[Steffen Hoffmann]

While the trace-back springs from a call of AcctMgr during a new-user-registration action, it runs fine through TracNotification. The failure is in the sender socket inititialization for the configured SMTP client. socket.py doesn't work, obviously for the getaddrinfo doesn't yield a valid connection, right? So this is most likely a local installation/configuration issue, and the OP needs to fix the email setup in [notification] rather than hoping that this is a plugin issue.

As a side-note, please don't let us without

• some human-written not about the issue and how to reproduce
• a valid email address, since anonymous bug reports tend to not work for plugin maintainers - they have a hard time to reach back to the reporter, if they get any additional feedback on the subject at all

so all-in-all this is a negative example, how you shouldn't throw your issues back at developers, respectfully.
