You can also ban extensions within Imail using rules. Here's an example of a rule that bans attachments that are executables with the .exe externsion. It does this by forwarding any message with an attachment that ends in .exe to NUL (which effectively discards it).
B~name=".*\.exe":NUL If you place the text above in a plain text file named rules.ima in the folder that contains that mail domain it should do the trick. The only downside is there isn't a whole lot going on in the logs to let you now when this happens. You could also choose to forward all mail that meets this criteria to a quarrantine mailbox account that you check out. Just add more lines if you want to ban other extensions (like .com or .cmd) I would go to the IPswitch site and check out rules processing, it's an extrememly powerful feature of the imail server. Hope this helps, Jeff Here's a summary of the IPswitch knowledgebase article. --------------------------------------------------------- Question/Problem: How can I prevent .exe files from being sent to my users? How can I give myself the ability to monitor these types of messages? Answer/Solution: The period is a special character (in regular expressions). Try this: B~name=".*\.exe":NUL In versions before 6.04 use the punctuation escape (\p): \pexe B~name=".*\pexe":NUL to remove all messages containing attachments with any filename ending in .exe. Note that this rule will delete all incoming messages containing attached files with .exe extensions. Note that only the first 32K of a message is checked. Please refer to page 78 in the IMail 6 User's Guide under Limits. Rules are written to a file, rules.ima in the TopDirectory for your domain or in a user's mailbox directory. ---------------------------------------------------------- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Monday, January 14, 2002 4:00 PM To: [EMAIL PROTECTED] Subject: [Declude.Virus] Banned Extensions Scott, We host multiple domains that use the Declude software. While we want to use the Banned Extensions feature, we cannot without the ability to do it per domain. Some domain owners may want us to ban .EXEs while others don't. Is this something we can expect for the future? Thanks, Don --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] This E-mail came from the Declude.Virus mailing list.
