Block the Melissa virusThis page tells you how to configure sendmail so it will block the melissa virus. Actually, it refers you to another page, but there ya go.
What virus?The Melissa virus comes as a Microsoft Word attachment. It will duplicate itself to the first 50 names in your Microsoft Outlook address book.
The fixSendmail, Inc have created a fix at http://www.sendmail.com/blockmelissa.html which is a patch for this virus. The script at that location is kind of hard to copy and paste, so I’ve duplicated it here. But be sure to read the sendmail link and replace spaces with tabs as they suggest.
By the wayBy the way, the script originally provided by Sendmail contained a space at the end of LOCAL_RULESETS line which will cause the following error:
Mar 29 08:15:47 ns sendmail: NOQUEUE: SYSERR(root): /etc/sendmail.cf: line 1034: unknown configuration line " "
I’ve emailed them about that. But if you get the above error, you now know what to do.
