Please create DNS records instead of CNAME:
lists.exim.org. 300 IN MX 10 lists.exim.org.
lists.exim.org. 300 IN A 37.120.190.30
Or accept emails to lists sent to <listname @ cumin.exim.org> .
Else some people trying to post to lists get "unknown user"
because sendmail "canonicalises" hostnames.

smtp_receive_timeout is expanded in smtp_setup_msg function in smtp_in.c
at the start of a SMTP session.
