Good news. I have now successfully subscribed. The problems I experienced were due to the left side of the email address being greater than 64 characters. In my case, my early attempts generated addresses like this:
dev-allow-sc.1291348253.bfbldlecgalabaakgefi-stephen.vincent=sas....@activemq.apache.org Which have the left side greater than 64 characters and thus failed. I finally noticed one less than 64 characters: dev-sc.1291869618.bmolhjgadpfjgeagonlp-stephen.vincent=sas....@activemq.apache.org That one worked because it is less than 64 characters on the left side. Thanks, sv sasasasasasasasasasasasasasasasasasasasasasasasasasasasasasasasas Stephen Vincent
