Messaging Gateway

Hi everyone. I have a curious problem regarding email attachments. When a Solaris 10 server sends mail thru Brightmail Gateway the attachment (textfile.txt) is renamed to filename and the .txt extension is stripped away. What makes this even more odd is that there are no filters for the domain where the mail is coming from. The Brightmail Gateway is used to relay mail outside and there is no inbound traffic. Has anyone ever run in to problems with Brighmail + Solaris 10? Could there be some compatibility issues with Sendmail & Brightmail? Any help is highly appreciated!

It may be that the sending application is not correctly formatting the attachment.  You should look a copy of the e-mail as it arrives and see how the attachment is "attached"   Is the sending application (not sendmail) correctly naming the file in the mime sections?

You could try a content policy with a incident.  Once you capture an event, on your control center enable the support account, and go to
    cd /data/bcc/work/cfi

You will find a copy of the e-mail in a .eml file a few directories down.

$ find . -name *.eml
./cfi/00/00/00/mail12692750840751000.eml
./cfi/00/00/00/mail12692756632851001.eml

Take a look at it and see if the mime filename is correct.

You can use something like WinSCP to connect to the CC and pull the file down to your PC.

Thanks for the hints Cricket17 but the problem was not in the Brightmail Gateway. It turned out that the receiving end had some configuration issues in their spam filter. The name (and somehow the position) of the attachment triggered some action in the receivers spam filter, which caused the attachment to be renamed. Anyway, thanks for the help.

Welcome.
