I'm not sure that these are conflicts.
As I see it, it's legitimate lookups for the users who are the members of maillist
I thought that's correct behavior, am I wrong?

Try capturing the LMTP traffic between Dovecot and Exim? I'm not sure if there's a good way to capture traffic from UNIX sockets, but at least if Exim and Dovecot talk via TCP there are many ways.

The different LMTP ids and dates are added only when there are different DATA commands, which would mean that Exim has sent separate RCPT TO + DATA commands for each of these mails. But that kind of conflicts on your logs that show tons of SQL lookups one after another..
