Hi Ham,
Its seems that your problem is that bulk_mail__new() is not on the db. So that plsql might not exists. If it only exists in oracle (maybe.. bulk_mail.new), then you will have to port it. Or it maybe that the plsql exists but accepts a different argument, either you look at pg_procs table or look at the sql files of bulk mail package. Do we need this for PT&T?
Sorry not much help now, I need to concentrate on PGDC.
