This basically says that Dovecot's SMTP client is being noncompliant,
because Exim doesn't advertise PIPELINING extension. But I'd rather not
add more code to fix this, since PIPELINING gives you a little bit
better performance anyway and you can most likely fix this by modifying
Exim's configs in some way (I can't believe Exim wouldn't support
PIPENING..).
