@stop It will maybe stop some spam, but also many legitimate mail. So much servers and software out there that are half-broken.
This solved most spam problems for me:
acl_check_mime:
deny
message = no spam here
mime_regex = (?i)https?:://[a-z0-9]+\\.su : (?i)https?:://rambler\\.ru
accept
note that it SHOULD be double colon as this decodes to a literal colon in exim4's regex language, same with double backslashes. (normal colon is item separator) -
@sebastian it would be an additional domain. so legitimate emails would arrive

Who, more than I, totally HATE emoji?
lol I hate emoji after it caused so much problems with Microsoft Outlook and email backups from said program combined with emoji in subjects.
Wrote an subject filter in exim4 (took 3 days to debug and get working propely) that totally eradicate anything that isnt ISO-8859-1 from the subject line, then converts the rest to UTF-8 (because said IMAP client isnt following standards).
it also converts ISO-8859-1 characters in subjects to UTF-8 even if the original subject is declared to be UTF-8, because obviously some software (especially newsletter software) are transmitting ISO-8859-1 subjects that are declared to be in UTF-8 (but the opposite isn't true).
And also cuts subject to 100 chars, because too long subjects are a problem too. Same with date headers, I replace them with the server date/time because some software are sending Date: 1970 Jan 01 00:00:00, because some of these erronous headers are put by some mailing list software, aswell as causing problem in OEM clients like Samsung Mail.
Problem solved, all IMAP clients happy on internal network.
