[Dovecot] Windows Mobile and IMAP proxy

Hi,

We are running Dovecot proxies in front of our Dovecot IMAP servers, and were having problems with Windows Mobile clients not being able to connect. The clients would send a LOGIN command, and immediately after the succes reply a LOGOUT command.

It turns out the Windows Mobile IMAP client gets confused by the IMAP proxy first sending the command tag in the reply and then, in a seperate packet, the rest of the line. Although not being able to handle this looks like a very bad design to me (how can one ever expect to read a full line in a single read() call?) I fixed it in our Dovecot proxies because we do have clients that want to use it.

Attached is my fix for the problem.
