for lols i clicked on test & immediately was rewarded with with this:


Also asked on Apache OpenOffice forum

after i filled in my known-valid email creds:

LibreOffice could not connect to the outgoing mail server. Check your system’s settings and the settings in LibreOffice. Check the server name, the port and the secure connections settings

<class ‘poplib.error_proto’>: -ERR EOF, traceback follows
File “/Applications/”, line 391, in connect
self.server = poplib.POP3(server, port, timeout=tout)
File “/Applications/”, line 107, in init
self.welcome = self._getresp()
File “/Applications/”, line 152, in _getresp
resp, o = self._getline()
File “/Applications/”, line 136, in _getline
if not line: raise error_proto(’-ERR EOF’)

and then l.o. hangs, gotta kill it:-\
