Conversion entry parameter value wildcard matching

The values of conversion entry parameter values may be specified as literal strings, or using wildcards as in MTA  mapping table entry patterns.

For instance, in-dparameter-name-0=filename; in-dparameter-value-0=&#x2a;.wpc; would match any Content-disposition: header filename parameter that has a   extension. Or in-dparameter-name-0=filename; in-dparameter-value-0=&#x2a;.wp$&#x5b;cd56&#x5d;%; would match any Content-disposition: header filename parameter that has a ,  ,  , or    extension.
