Yes, I have:
[root[at]monstera lists]# exim -v -bv userlist
user1[at]itelsib.com
<-- itelsib-adm[at]itelsib.com
router = localuser, transport = local_delivery
user2[at]itelsib.com
<-- itelsib-adm[at]itelsib.com
router = localuser, transport = local_delivery
userlist[at]itelsib.com
<-- itelsib-adm[at]itelsib.com
router = localuser, transport = local_delivery
