Dynamic 1007 is for a fixed salt length of 3. I think you need to write a new dynamic format in dynamic.conf. The below is untested but might work fine:
[List.Generic:dynamic_1351]
Expression=md5(md5($p).$s) (long salt)
Flag=MGF_SALTED
Flag=MGF_NOTSSE2Safe
Flag=MGF_KEYS_BASE16_IN1
Func=DynamicFunc__set_input_len_32
Func=DynamicFunc__append_salt
Func=DynamicFunc__crypt_md5
Test=$dynamic_1351$daa61d77e218e42060c2fa198ac1feaf$SXB:test1
BTW, the salt separator is '$' and -field-separator-char does not change that. If some salts contain '$' I believe they'll have to be hex encoded.
