I run loads of small business email systems and have done for decades, in the UK. That thing has GTUBE at the end of it, which doesn't look quite as dodgy as EICAR to humans. lol. Without the GTUBE string, rspamd scores 10.50, which is flagable by default. With it, rspamd scores 15.0 (ie whatever REJECT is set to) and ignores the rest of the message. rofl.
