These are the same as what is on the terminal, so unfortunately that doesn't help.
TK> What is that .fml file?
MSG*.FML These files are created in the message base
directory when FMail is running in message base
sharing mode. Normally FMail will append these
files to the normal message base files, but it can
happen that this is not possible. FMail will retry
to append them to the normal message base files the
next time it is started.
Bye, Wilfred.
