CACHE_SKIP_MAX
From Messaging Server Technical Reference Wiki
TCP/IP-channel-specific options: CACHE_SKIP_MAX (integer)
This SMTP/LMTP client option specifies the maximum number of messages that will be skipped after a failure. The number of message skipped increases each time another delivery is attempted and fails. The default value is 32.
This option is new in MS 8.1.0.7. There was no limit in previous versions.
