554 5.7.1 Gtube pattern
Environment: two-server (edge & mailbox) Zimbra FOSS, spamassassin replaced by rspamd.
I want to switch off this rejecting because I need to manage all messages by rspamd.
I can't even realise which service generates "554 5.7.1 Gtube pattern". Please tell me the way to dig in!
Best Regards.
