[Rspamd-Users] Reminder mail from Google Calendar hits R_SUSPICIOUS_URL

[Yasuhiro KIMURA]

Hello all,

Recently rspamd on my home server judges reminder mail from Google
Calender (https://calendar.google.com/) as spam. I checked
X-Spamd-Result header and found there is following line.

	 R_SUSPICIOUS_URL(5.00)[www.google.com];

It seems 'www.google.com' is regarded as suspicous URL. But obviously
this URL isn't suspicous one and, futhermore, it is quite natual that
this URL is included in mail from service of Google. So this is
clearly false positive.

Then how can I fix it? I read on-line documentation of rspamd but
couldn't find description about this symbol.

Best Regards.
