Any version.
This Error Reference is intended for:
Any audience.
Summary
Your server's domain name resolution (DNS lookup, name lookup) is not working correctly for some reason. Typically, this problem surfaces when sending mail from the Plone site, such as password recovery mails or new account registration mails.
What to do
Ask your system administrator to configure the network correctly. Note that this could also be due to a firewall blocking nameserver access from the host, in which case your network administrator would be the person to call.
Other indicators
- If you receive this error, you will also see that commands that access the network given in a command shell, such as
ping plone.org, also are failing.

Technical description
Quoted from the Python documentation:
- exception gaierror
- This exception is raised for address-related errors, for getaddrinfo() and getnameinfo(). The accompanying value is a pair
(error, string)representing an error returned by a library call. string represents the description of error, as returned by the gai_strerror() C function. The error value will match one of the EAI_* constants defined in this module.
hostname not FQDN is possible cause, too.
For example 'server1.domain.tld' instead of just 'server1'.
hth,
