changed FileNotThere text.dat entry to FileDoesNotExist which displays the file
path.
Now check if the directory exists before checking the available disk space
before allowing file uploads and report the correct error (using
DirectoryDoesNotExist) if the directory is missing (a common mistake).
Overhaul viewfilecontents() - wow, I can't wait to re-write all of this moldy

not have the default entry (*.synchro.net) allow SPAM from DNSBL-listed servers

A dnsbl_exempt.cfg entry of "*.synchro.net>" would be required to match

positive DNSBL result on the sender's IP address will be ignored.
* Automatically adds ("white-lists") recipients of mail that was successfully
delivered by the sendmail thread to the dnsbl_exempt.cfg file if they're not
already listed.
* Local submit performance improvements: don't perform ip.can, host.can or

localhost or the same IP as the server is listening).

xmodem_get_ack() now returns an int (ACK on success)
Use 3-second block 0/1 timeout to follow ymodem.doc example
Fix the use of xm.max_errors
Support (configurable) fallback from Ymodem-send to Xmodem-send
sexyz.ini can be used to disable 1024-recv, CRC-send and G-send support
Document more sexyz command-line options to enable legacy x/ymodem modes

Stop using ((block_num-1)*(xm->block_size)) as the offset.
Use sent_bytes instead.
