I had problems with the scheduler dumping core using zmailer-2.99.42 under Solaris-2.5.1, but non with zmailer-2.99.41 under Solaris-2.5.1. The scheduler under 2.99.41 handles mainly smtp ta's, and the scheduler under 2.99.42 handles mainly mailbox ta's. I don't know whether that is a factor or not. --Eric Riehl
