message is bounced).
debug_peer_level
Verbose logging level increment for hosts that
match a pattern in the debug_peer_list parameter.

List of domain or network patterns. When a remote
host matches a pattern, increase the verbose logging

search for an A record instead deferring mail

delivery loops.
