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..).
Thanks for your reply. Indeed exim supports PIPELINING by default:
Oh. Well, see if the attached patch helps? If it does, I'll add it to next version.
