I am trying to make POP3 proxy/gateway, I am working linemode ON as it
a CRLF lined protocol so its easier.
But I noticed that not all lines are sent back to POP3 client, so
e-mail (especially the ones with attachements) get corrupted.
Each time I go into OnDataAvailable on server-side socket I loop into
ReceiveStr() and call TWSocketClient.SendStr() on client socket for
each line.
Is there something wrong with this scheme
I assume you have set LineMode to true.
No need to loop beause ReceiveStr() will receive the complete line received
so far and if more lines are available, then more OnDataAvailable events
will be triggered.
do I overload the WinSock internal buffer ?
No risk. TWSocket buffer outgoing data in his own internal dynamically
allocated (only limited by available memory) and move data to winsock when
winsock notifies about space available in his buffers.
should I use a man-in-the-middle StringList buffer
and when OnDataSend on client side I loop SendStr un until no more
lines from StringList buffer ?
Defenitely not.
