If you adjust the massmail parm too low your system may reject a newsletter from IBM(it is an example) Because the antispam screening cannot make the difference between 200 identical incoming spam mails and 300 identical incoming newsletter for the announcement of system W . On the other hand if you adjust at 350... then you let some spam through The exclude list also can be tricky on web access. (i remember not being able to look at sites speaking about DB2 propagator) The reason was that our subscribed list was mentioning *gator* as a spyware. When you receive 2 or 3000 attacks per hour , you need an automated system And automation as sophisticated as it may be has its limit because the spammer are very clever and moving fast .

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
Re: Website Blacklists
Spamming can cause this. Once, a long time ago, a customer was unable to receive any email from me. We found out that their site was automatically blocking all email from IBM because they said they had been spammed from our domain. I don't know if there had really been an infected machine inside IBM, or if somebody outside had just successfully spoofed the sending domain. --Roger Bolan IBM Mainframe Discussion List wrote on 02/17/2009 10:18:53 AM: > Greetings, >I came across a weird situation late last week.

Re: Website Blacklists
Kinda, in reverse. One of my new team mates, tried to subscribe to IBM-MAIN via the web interface. The confirmation email never shows up. Then tried to send the subscription request by email. My email team here traced the email outbound from our site, and BAMA.EDU accepted the email, but never send the confirmation back. Almost like my domain - 53.com is somehow blacklisted by them! Same problem at Marist.edu. But I can subscribe to the RACF-L list at UGA.EDU and that works fine. I've tried contacting Darren here, and Harry Williams at Marist and never hear back on the matter.
