And it has only taken a week or two to figure out how to prevent that...
cyrusv2.mc patch:

  #       This sample mc file is for a site that uses the Cyrus IMAP server
  #       exclusively for local mail. This requires Sendmail 8.10 or later.

  OSTYPE(linux)
  define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')
  define(`confTO_IDENT',`0')
  
  dnl setting cyrus as the trusted user will make it easier to pass
  dnl Sendmail's safefile checks.  however, it means that someone with the
  dnl "cyrus" password could easily become root.
  dnl define(`confTRUSTED_USER', `cyrus')
  
  define(`confLOCAL_MAILER', `cyrus')
  
  dnl if you aren't using Sendmail 8.12, you might need to remove
  dnl the following feature.
  FEATURE(`preserve_local_plus_detail')
  
  FEATURE(`nocanonify')
  FEATURE(`always_add_domain')
  MAILER(`local')
  MAILER(`smtp')

--------------------

Dump `EnvToL/' from R= and you get working sieve vacations.
The fix turned out to be rather trivial.

Does anyone spot problems with this?
