I'm trying to send a test message with gtube signature via telnet smtp-session and getting a reject message "554 5.7.1 Gtube pattern":
Code: Select all
$ telnet mx.domain.com 25
Connected to mx.domain.com.
Escape character is '^]'.
220 mx.domain.com ESMTP Postfix
mail from: firstname.lastname@example.org
250 2.1.0 Ok
rcpt to: email@example.com
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>
Subject: test message
554 5.7.1 Gtube pattern
(I replaced the first asterisk by underscore in gtube signature before posting this in order to forum's notifications can pass spam filters)
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!
