- Regrettably, there is no way (with any of the versions of sendmail in 4.52)
- to use a nameserver for host name lookup and NIS for mail aliases.
- /usr/lib/sendmail.nis is entirely useless if you demand DNS name service, and
- /usr/lib/sendmail.named will not use NIS for mail aliases regardless
- of what's in your /etc/vis.conf file. (This is the biggest hole I've
- noticed in the otherwise very nice /etc/vis.conf setup.)
-
- To cope with the perfectly sensible desire for centralized mail aliases
- together with DNS name service, we have entirely switched to a slightly
- modified version of sendmail which can use MB (mailbox) records in a DNS
- pseudo-domain as the source for mail aliases. This version of sendmail
- is available from ftphost.cac.washington.edu. Building was no problem
- under RISCos-4.52 (or SunOS or Ultrix). This use of MB records is
- described as experimental, but we've been very pleased with how it all
- works.
