Hi, I went through the entire install process except for the PDF and image scanning parts of it. The entire system worked wonderfully for about three months, then last week some users started getting blank messages with the MailScanner signature and nothing else. Since I administer this box, and no one else has access, I know that nothing was modified by any carbon based life forms. Nothing was upgraded, no config changed - nothing. After some digging around, I changed one settings in /etc/MailScanner.conf from Lock Type = posix to Lock Type = flock - no luck. At the moment, the Scan Messages = No so that incoming mail is at least delivered. Oh, it is running on Ubuntu 8.0.4 Any ideas? Thanks, Jay
Hey, Thats a very weird problem you're having. You said it worked for 3 months and then started doing this? I've been running mine since this guide was posted, but never had any such development. Do you see the mails coming in through the mailwatch interface? Also, are there any errors in your mail.log while this problem is taking place? Post your mail.log, atleast the last section of it so that I can take a look. Also, post your main.cf and master.cf files. Thanks, Rocky
Hi, I could not see any errors in the log when it happened, and the relevant mailwatch log entry indicated that the message was the right size and was delivered. We have verified the following: - Not attachment specific - at various times attachments of every kind were stripped along with the content. The message sent a few minutes later was delivered fine. - Not recipient specific - different recipients of completely different messages reported the issue. - Not sender specific - Once I set the Scan Messages to No, the problems went away, but that defeats the whole purpose, no? Basically, I have not been able to establish a pattern. Here is my master.cf ------- # # Postfix master process configuration file.

Hey, Make sure the following line looks like the below in MailScanner.conf: "Quarantine Whole Messages As Queue Files = no" Thanks, Rocky
