This is one of the problems with automated solutions! A site as reputable as IBM should not have been blocked. There MUST be some human over-sight. One company I worked for put in SPAM blockers in, and then reported on the success. Their indicator was the number/percentage of messages blocked. Absolutely nothing about false positives or negatives. I review every message that is marked as SPAM and report false positives to my service providers. Of course, I also report the false negatives. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
