Cannot send notification email to

[ahadobas]

Hello,

I get this error after a job is done and wants to send a notification email:
----------
Cannot send notification email to "****@***.**".
CURLE_COULDNT_RESOLVE_HOST: Could not resolve host: api.freefilesync.org [curl_easy_perform]
----------

How can I avoid this error?

My nslookup and ping are also working fine. This is something on the OP's computer/network causing an issue
