Hi, we use reject_unverified_recipient and have
alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases after changes in aliases and issuing postalias /etc/aliases verify_cache.db seems to get corrupted or at least not updated properly as new/updated entries do not get correctly verified and postfix logs: close database /var/lib/postfix/verify_cache.db: No such file or directory > (possible Berkeley DB bug only a postfix stop, rm verify_cache* , postfix start helps. are there known limitations?
