I moved /var/spool/MailScanner to a different disk and now I see this in the log when starting MailScanner..:<br>
<br>
<br>
Your "Incoming Work Directory" should be specified as an absolute path, not including any links. But I will work okay anyway.<br>
<br>
<br>
Can I just ignore this or should I change the Incoming Work Directory path?<br>

I think I understand that blowback problem is when email is sent, using for example my address, to many other domains and all the flack (blow back) comes back to me.<br>
<br></div>I am wondering if this watermarking is of any use in a type of SPAM we now frequently see. It is where email is sent to a list of addresses, all at our domain, and the from address is also the first address in the address list. Everyone else thinks the first person sent it. Our gateways send such email to Exchange and any communication back to the sender is entirely within Exchange and never comes back through the gateways again. <br>
<br>In this kind of SPAM I have always considered it of no use. Am I wrong in my thinking?<br clear="all"><div><div><br>-- <br>Robert Lopez<br>Unix Systems Administrator<br>Central New Mexico Community College (CNM)<br>525 Buena Vista SE<br>
