If you are referring to "PIPELINING," then the answer is No. The current versions of our POP3 Server do not support the PIPELINING capability. You can issue a series of DELE commands, but they must be separate transmissions. In other words, you could NOT construct a buffer consisting of multiple commands and then issue them in one "send" tranmission. If you did, the POP3 Server would only execute, and respond to, the first command in the transmission.
: Will it support issuing the dele commands in batch viz:- if i am extracting 100 mails i will not issue the dele command after every retr command instead i will issue it in batch after retreiving all the mails.
