Well, you want this: enable_long_queue_ids = yes ... but that won't help in one of the cases you mentioned, that of DNSBL blocking. Also, the customer won't know the queue ID, but it will be found in headers, unless of course it was blocked prior to DATA, in which case there's no queue ID. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
