Hi<br />
<br />
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.<br />
<br />
My questions are <br />
<br />
a) Is this considered necessary by the wider community<br />
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)<br />
c) Is it conceiveable to block HTML mails and is there any advantage? Or does blocking take place on attachments by and large?<br />
<br />
We are using Exchange 2003 Sp2, Outlook 2003/2007 clients. Apologies in advance, I know this may sound like a daft question :)<br />
<br />
Thx

Blocking .htm files and relevance to rich text/ HTML emails

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.
