TCP/IP-channel-specific options: CACHE_SKIP_MULTIPLIER (float)
This SMTP/LMTP client option controls how the number of messages skipped increases after another delivery failure. This floating point value is multiplied by the current skip value and the ceiling of the result becomes the new value. It defaults to 3.0.
This option is new in MS 184.108.40.206. The value was fixed at 3 in previous versions.
