Topic: files with .com in file name getting blocked
i cannot receive incoming or send outgoing messages if the file attachment name contain the text " .com" anywhere in the file name.
example if my file attachment name is : abc.com.txt
it gets rejected
So it looks entire file name is analyzed for the extension check.
my /etc/postfix/mime_header_checks file contains the following text
Is this is a known standard behavior required from security point of view ?
if not how can i modify the regex so that only files ending with .com extension will get blocked?
further on csr certificates attachments link example abc_com.crt files are also rejected with the following error
550 5.7.1 message content rejected
how do i resolve the above ?
