BCC does not work on exim

[abubin]

I seems to have problem receiving BCC mails. Cannot receive at all.

I have setup mails from users to forward to one single general account. Then my local mail server will retrieve mails from this single account and distribute mails according to recipient email address.

Anyone know how and where to tackle this problem?

Here is more info on what i did.

I tried sending email from a gmail account. 2 email account are involved. [email protected] and [email protected].

[email protected] is a pop3 user email account.

[email protected] is forwarded to [email protected]


1) TO:[email protected] and BCC:[email protected] :-

[email protected] receive the mail but not [email protected]


2) TO:[email protected] and BCC:[email protected] :-

[email protected] receive the mail, so does [email protected]


Verdict. Mail forwarding does not with with BCC.

Anyone wanna test this on their cpanel server and let me know whether this problem is cpanel/exim related or just my server.

Thanks in advance.

Works on my server. Just tried it.

darn! it's my server then...what else can i check?

mailscanner?
exim?

Could be mailscanner, maybe. Also check any filter settings that you might have. I doubt exim would be the culprit.

 

[abubin]

could it be that because of header changes by mailscanner? because I think the problem is that my mail server program Winroute Pro is unable to handle that BCC mail created through forwarding.

But strangely, it was working fine on the ensim server running mailscanner also.

Found this that might be helpful :

Q. We cannot receive email to users in the BCC field. The message is always routed to the postmaster account. Is there something configured incorrectly?
A.
BCC only works with SMTP mail. By definition, the carbon copy is 'Blind'. There are no headers in the message which can be parsed using the POP3 method that would provide the address.

The only hope for these kinds of messages is to get the ISP to stamp the message file with the delivery information from the SMTP session during delivery to the ISP. For example, when the person sends the BCC message to the ISP hosting the mail, some of them stamp a header called 'Delivered-To:' into the message. VisNetic MailServer could pick up on such a header if it existed.

Is there anyway I could stamp a header "Delivered-To:" in exim?

Here is a sample of the said mail :

Envelope-to: [email protected] 
DomainKey-Signature: a=rsa-sha1; q=dns; c=nofws; 
        s=beta; d=gmail.com; 
        h=received:message-id:date:from:reply-to:to:subject:mime-version:content-type:content-transfer-encoding:content-disposition; 
        b=DZpg6xiWI7oQkCRD6Y6iw5UFFZS5zKkaljALhbCHn7L6vijzv6o9dXpuVb96jSVHIaIT2EXExit64L1hNV6MaXE6TWP3cbh+31ZwzJ2b7E/qz/NdBMmo/czX8B/Rgb4inFaegLxS2zO6fCiCdX8Rwq2djwoAo8JGqFeq8itW4X8=

this is for mei only

This mail is sent TO:[email protected] and BCC:[email protected] This is the copy for [email protected] as you can see in the Envelope-to section. But it didn't get delivered to mei but instead went to my postmaster mail on my winroute pro email software.

Any help would be appreciated.

Seems that we have similar situation here. Did you manage to solve your problem?

See if this is unchecked in tweak settings

Silently Discard all FormMail-clone requests with a bcc: header in the subject line

With the forward if this is checked could cause the BCC to be discarded

found out that this problem is more to do with our pop3 retrieval software. Older pop3 retrieval software only allows sorting through certain headers like "Delivered-To" or "CC". But with exim, it uses "Envelope-To" to avoid a lot of spamming software which exploit "Delivered-To" header. So, you only choice is to change pop3 retrieval software (which we did) or to learn up exim programming and add BCC fields to "Delivered-to" or whichever header your pop3 retrieval software is using for sorting user mails.
