Was just wondering if anyone else had noticed an increase in spam slipping through in recent weeks since the 8.51 update was applied to any of your servers?
Have noticed a lot more coming through, and it's seemingly to do with including the receiving email addresses domain being included with an =<domainname> before the @ symbol.
For example:
MAIL+FROM:<KidsLiveSafe-scott=mydomain.com@swmdco.com>
This would allow any email through where the email being sent to the recipient was, in appearance, containing the sending email address still.
Any other people noticed this issue?
Kind regards,
S
