As I use mbse the answer is err - yes as far as I know. - checking docs.
Mail packets for Type 2+ - following the FSC-0039 standards with a fall back to old stone age packets with messages limited to a maximum of 429,467,295 bytes, see spec notes :
Description. mbfido is the program to process fidonet mail and files. In order to run mbfido you must first start mbtask, this is the daemon which controls all bbs activities. To prevent that mbfido will run more than once at the same time a lock is placed in the protected inbound with the Pid of the running mbfido program. The gateway to and from internet is also handled by mbfido.
Specifications. The recognized mail packets are type 2+ following the FSC-0039 standard with a fall back to the old stone age packets. Can handle messages of maximum 429,467,295 bytes, or less if you have less memory available, the practical limit is about 1 Meg. Note that most mail processors are only guaranteed to work to maximum 16 KBytes. Experiments between 1997 - 2003 in the LINUX echo show that this is still true, although most tossers seem to process mail up to 32 KBytes.
