Indeed exim supports PIPELINING by default:
# telnet mail.apisoft.pl 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 zeus.apisoft.pl ESMTP Exim 4.76 Wed, 16 Nov 2011 14:55:25 +0100 EHLO test 250-zeus.apisoft.pl Hello localhost [127.0.0.1] 250-SIZE 52428800 250-PIPELINING 250-AUTH LOGIN PLAIN CRAM-MD5 DIGEST-MD5 250-STARTTLS 250 HELP and PIPELINING seems to work fine. But maybe there is a problem with smtp dialog between dovecot and exim.
