That is interesting. What kernels do you use? Or do you use HVM (that
would not really count ...)? I tested cyrus-imapd in three different

* CPU:  intel P4
  Xen:  3.0.2 x86_32 (self built)
  Dom0: CentOS-4.4/ (self built) 
  DomU: CentOS-4.4/ (self built) 

* CPU:  intel core 2 duo
  Xen:  3.0.3 x86_32p (from FC6)
  Dom0: FC6/2.6.18-1.*.fc6xen 
  DomU: CentOS-4.4/2.6.18-1.*.fc6xen (from FC6, rebuilt) 

* CPU:  intel P3
  Xen:  3.0.3 x86_32p (from FC6)
  Dom0: FC6/2.6.19-1.*.fc6xen 
  DomU: CentOS-4.4/2.6.9-44.ELxenU (from Jason Baron)

and in each case cyrus-imapd fills up the maillog with 

  DBERROR db4: Berkeley DB library configured to support only DB_PRIVATE
  DBERROR: dbenv->open '/var/lib/imap/db' failed: Invalid argument
  DBERROR: init() on berkeley executed
  DBERROR db4: environment not yet opened
  DBERROR: opening /var/lib/imap/deliver.db: Invalid argument
  DBERROR: opening /var/lib/imap/deliver.db: cyrusdb error
  FATAL: lmtpd: unable to init duplicate delivery database

Yes, i removed /lib/tls and /usr/lib/tls. The only workaround i found
yet was rebuilding db4.

Ok, send me the hotel's address! I'll send you my favorite beer from
northern Germany. It is a bit austere - if that is the correct word - is
that ok4u?
