While you are at it, use the 'plain text' option or whatever GMail is calling it these days to send mail to this group. Questions regarding 'MailScanner' should be directed at that group's mail forum. In any event, using an outdated version of any software may pose a problem. I would definitely use the latest versions of Postfix, and if you must use it, MailScanner. BTW, your version of 'Dovecot' is not current either. I can only imagine what version of ClamAV you have installed. There were several security issues with some of the older versions. I would definitely consider keeping that current. -- Gerard postfix.u...@yahoo.com TO REPORT A PROBLEM see http://www.postfix.org/DEBUG_README.html#mail TO (UN)SUBSCRIBE see http://www.postfix.org/lists.html There is no likelihood man can ever tap the power of the atom. -- Robert Millikan, Nobel Prize in Physics, 1923
