I'm afraid I don't understand you. Look at this quite legitimate line:
accept condition = ${lookup{$local_part@$domain}lsearch{/etc/dovecot/aliases}{yes}}
Doesn't this line mean that the right part of the expression is err... hmm... a condition?

OK, I have changed my expression to
accept condition = ${if or {\
eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/aliases}{yes}}{yes}} \
eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/users}{yes}}{yes}} \
} {yes}}
and still it's not the thing:
failed to expand ACL string "${if or {eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/aliases}{yes}}{yes}} eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/users}{yes}}{yes}} } {yes}}": each subcondition inside an "or{...}" condition must be in its own {}
Then into
accept condition = ${if or {\
{eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/aliases}{yes}}{yes}}} \
{eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/users}{yes}}{yes}}} \
} {yes}}
and still:
failed to expand ACL string "${if or {{eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/aliases}{yes}}{yes}}} {eq{${lookup{$local_part@$domain}lsearch{/etc/dovecot/users}{yes}}{yes}}} } {yes}}": missing 2nd string in {} after "eq" inside "or{...}" condition
Can you possibly please reword my combined expression into a working one?

I agree. Exim is my favorite opensource MTA.

Even people with some background in CS and/or programming often need
and appreciate good cookbooks and howtos.
BTW while googling for the solution, I've found quite a few questions in mailing
lists and Web-fora where people are frustrated by exim's nested conditions.
