EneTar
Is there any way to create an email filter for an account john@mydomain.com to filter all incoming emails that have john@mydomain.com to the bcc field ? I would really appreciate any help

    Thank you for your answer I have created a filter for the To: header by looking for undisclosed-recipients:;
    . While this doesn't answer the question really it helps.

    Trying to setup a filter with 2 regex rules for bcc: The first regex (rule) checks if there is john@domain.com at the Delivered-To or the Envelope-to headers (?:[Ee]nvelope-[Tt]o\:\s*john\@domain\.com)|(?:[Dd]elivered-[Tt]o\:\s*john\@domain\.com)
    So it should work in a filter where [any header] [matches regex] [1st regex] the second regex (rule) checks if john@domain.com is not included in the To: and CC: headers (?!(?:^[Tt]o\:\s*.*john\@domain\.com)|([Cc][Cc]\:\s*.*john\@domain\.com))
    This should go [any header] [matches regex] [2nd regex] Combined those 2 rules with a logical AND inside the cPanel filter should do the job. But it doesn't. Do you see anything wrong?

    Hello, You may want to try using the "does not match" option for the operator and then utilize a normal regular expression (instead of using a negative regular expression for "matches regex"). There's some discussion of this on the following thread: Thank you.

    I think the reason is something else. I built the 2 regex above by inspecting the source of the test email messages from the recipient's point of view which means as soon as they are delivered to the inbox. Actually i tried to test just the first regex alone and I expanded it to: (?:[Ee]nvelope-[Tt]o\:\s*info\@domain\.com)|(?:[Dd]elivered-[Tt]o\:\s*info\@domain\.com)|(?:[Ff]or\s*)
    It works very well (confirmed by the cPanel test filter) for this: Return-Path: Delivered-To: info@domain.com Received: from my.hostname.eu by my.hostname.eu with LMTP id 4IBbNGmtbFr0NQAAnaC/hg for ; Sat, 27 Jan 2018 18:48:41 +0200 Return-path: Envelope-to: info@domain.com Delivery-date: Sat, 27 Jan 2018 18:48:41 +0200 Received: from sonic315-20.consmr.mail.ne1.yahoo.com ([66.163.190.146]:40241) by my.hostname.eu with esmtps (TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128) (Exim 4.89_1) (envelope-from ) id 1efRfe-0006Zf-OE for info@domain.com; Sat, 27 Jan 2018 18:48:41 +0200
    in reality though the actual email is not filtered. I guess that none of the 3 headers: are set during the time that Exim evaluates the filter. So how can we know what Exim sees at the time of the evaluation of the filter to build a proper regex?

    Hello, Support for custom filter rules using regular expressions is generally outside our scope of support, however you may want to try using the "does not match" option for the operator and then utilize a normal regular expression (instead of using a negative regular expression for "matches regex") to see if you notice any change in behavior. Thank you.
