6 Pingpong is just my (Daniel's) jestful collective name on the protocols that
7 share a very similar kind of back-and-forth procedure with command and
8 responses to and from the server. FTP was previously the only protocol in
9 that family that libcurl supported, but when POP3, IMAP and SMTP joined the
10 team I moved some of the internals into a separate pingpong module to be
11 easier to get used by all these protocols to reduce code duplication and ease
12 code re-use between these protocols.

16 In 7.20.0 we converted code to use the new pingpong code from previously
17 having been all "native" FTP code.

19POP3

21 There's no support in the documented URL format to specify the exact mail to
22 get, but we support that as the path specified in the URL.

24IMAP

26SMTP

28 There's no official URL syntax defined for SMTP, but we use only the generic
29 one and we provide two additional libcurl options to specify receivers and
30 sender of the actual mail.
