Can you provide some more information?  What SMTP server are you using?
Is the server running on the lwIP system, or on another system and lwIP
is operating as the client?  Can you get a packet capture to illustrate
the problems you're having?

As Piero said, it does sound rather like this is a problem with the SMTP
server or your driver, rather than lwIP, but some of the above should
help to pinpoint where things are going wrong.
