Blocking .htm files and relevance to rich text/ HTML emails
Posted on 2008-06-16
We have an external company trying to an email an attachment that is an .htm file. It is not getting through our SMTP Gateway which is configured to block .htm files as a security requirement.
My questions are
a) Is this considered necessary by the wider community
b) Disregarding the .htm attachment, does the fact that some emails are HTML formatted, and some are Rich Text, have anything to do with the problem? Or are HTML emails and an .htm attachment two different things (I assume they are)
c) Is it conceiveable to block HTML mails and is there any advantage? Or does blocking take place on attachments by and large?
We are using Exchange 2003 Sp2, Outlook 2003/2007 clients. Apologies in advance, I know this may sound like a daft question :)
