namespace Poco {

class Net_API MailStreamBuf: public Poco::UnbufferedStreamBuf
The sole purpose of this stream buffer is to replace
a "\r\n.\r\n" character sequence with a "\r\n..\r\n" sequence for
output streams and vice-versa for input streams.
This is used when sending mail messages to SMTP
servers, or
receiving mail messages from POP
servers.
See RFC 2181 (Simple Mail Transfer Protocol) and RFC 1939
(Post Office Protocol - Version 3) for more information.
{
public:
MailStreamBuf(std::istream& istr);
Creates the MailStreamBuf and connects it
to the given input stream.
MailStreamBuf(std::ostream& ostr);
Creates the MailStreamBuf and connects it
to the given output stream.
~MailStreamBuf();
Destroys the MailStreamBuf.
void close();
Writes the terminating period, followed by
CR-LF.

class Net_API MailIOS: public virtual std::ios
The base class for MailInputStream and MailOutputStream.
This class provides common methods and is also needed to ensure
the correct initialization order of the stream buffer and base classes.
{
public:
MailIOS(std::istream& istr);
Creates the MailIOS and connects it
to the given input stream.
MailIOS(std::ostream& ostr);
Creates the MailIOS and connects it
to the given output stream.
~MailIOS();
Destroys the stream.
void close();
Writes the terminating period, followed by
CR-LF.
MailStreamBuf* rdbuf();
Returns a pointer to the underlying streambuf.
protected:
MailStreamBuf _buf;
};
class Net_API MailInputStream: public MailIOS, public std::istream
This class is used for reading E-Mail messages from a
POP3 server. All occurences of "\r\n..\r\n" are replaced with
"\r\n.\r\n". The first occurence of "\r\n.\r\n" denotes the end
of the stream.
{
public:
MailInputStream(std::istream& istr);
Creates the MailInputStream and connects it
to the given input stream.
~MailInputStream();
Destroys the MailInputStream.
};
class Net_API MailOutputStream: public MailIOS, public std::ostream
This class is used for writing E-Mail messages to a
SMTP server. All occurences of "\r\n.\r\n" are replaced with
"\r\n..\r\n".
{
public:
MailOutputStream(std::ostream& ostr);
Creates the MailOutputStream and connects it
to the given input stream.
~MailOutputStream();
Destroys the MailOutputStream.
