Hello,
I'm having trouble with nested domainlists and cached lookup data, and
can't decide whether the problem is mine or Exim's ...
Exim 4.12. I've checked the Changelog for 4.14, and can't find anything
relevant. I've also checked the archive, though not exhaustively, so
apologies if I've missed something.
I decided to tidy up my configuration ("If it ain't broke, fix it till it
is") by splitting the local domains into "real" and "virtual" ones. I have
pruned it down as much as possible, and now have
domainlist real_local_domains = CFGDIR/domains/debug-real-domains
domainlist virtual_local_domains = lsearch;CFGDIR/domains/debug-virtual-domains
domainlist local_domains = +real_local_domains : +virtual_local_domains
and routers
lookuphost:
driver = dnslookup
domains = ! +local_domains
self = pass
transport = remote_smtp
no_more
virtual_aliases:
driver = redirect
allow_defer
allow_fail
data = ${lookup{$local_part}lsearch*{ALIASDIR/$domain_data}}
domains = +virtual_local_domains
file_transport = address_file
hide_child_in_errmsg
no_more
pipe_transport = address_pipe
qualify_preserve_domain
retry_use_local_part
The other relevant files are:-
debug-real-domains
::::::::::::::::::
my-real.domain.com
debug-virtual-domains
:::::::::::::::::::::
my-virtual.domain.com: debug-virtual-aliases
debug-virtual-aliases

virtual_aliases router: defer for postmaster@???
message: failed to expand
"${lookup{$local_part}lsearch*{/opt/exim_configuration/alias_info/$domain_data}}":
/opt/exim_configuration/alias_info/ is not a regular file (lsearch lookup)
... which looks odd because the first router claims to have cached the
data from the lookup, while the second says that the match has been cached
but the cached data is NULL.
If I change the definition of local_domains to
domainlist local_domains = CFGDIR/domains/debug-real-domains : \
lsearch;CFGDIR/domains/debug-virtual-domains
(i.e. don't nest the named lists), the output is now

Considering postmaster@???
.... it appears that the second router can find the cached lookup data OK.
Am I misunderstanding something, abusing something, or boldly going where
no man has gone before (and regretting it)?
