I have fully working setup of my mailserver based on OpenBSD with Sendmail 8.14.5 + Cyrus-SASL 2.1.25 + Cyrus-imapd 2.4.13 software.
Trying to add Majordomo mail list functionality to it, but Cyrus always checking that mailbox is present in system despite that its name is an alias in Sendmail "aliases" file or Majordomo "asliases.majordomo" file.Denis
