This may be an off topic question but I don't know where I would post such a question. I have a set of "quarantined" files all stored in gz files. And I want to have an automated program release them under special circumstances. These emails are essentially the full header and email before they are delivered in plain text. I have used mutt in the following fashion. Zcat qemail.gz > tmp.eml | mutt -a tmp.eml -s "test" recip@xxxxxxxxxx < /dev/null But this results obviously in sending a .eml file which works great on outlook express but other email clients are confused. If I were to figure out the encodeing for Outlook it would make it a .msg file. But this would confuse OE. I have found that Dbmail has the result that I am looking for. If I have a bounced messange from dbmail it will attach the original in its message, however the file type seems to morph depending on what program looks at the message. My guess it this deals with the MIME type, but I don't know either how to set this in a file or how to determine what type is needed to make it an email. Any thoughts, redirections, general suggestions are more than welcome. Thanks Steven Lamb
