Greetings list,
I've started merging various domains on a single server and tried
to realize a setup where I can have multiple alias files - one for each
hosted domain.
My current approach is to modify the standard system_alias router
in the following way:
system_aliases:
debug_print = "R: virtual_system_aliases for $local_part@$domain"
driver = redirect
domains = +local_domains
allow_fail
allow_defer
data = ${if exists{/etc/aliases.$domain}{${lookup{$local_part} \
lsearch{/etc/aliases.$domain}}}fail}
According to the tests I made, this seems to work like intended, but
does anyone see a problem arising with this config? Or is there
a smarter way to do it? I've googled and searched the list, but
didn't come up with a better idea.
Since my approach has the problem of not having a catchall
aliasfile to match all the standard aliases (postmaster, etc.pp), I
thought of enhancing it:
data = ${if exists{/etc/aliases.$domain}{${lookup{$local_part} \
lsearch{/etc/aliases.$domain}}} \
${lookup{$local_part}lsearch{/etc/aliases}}
But sadly that approach cannot work, as it only checks the catchall
aliasfile if the specific $domain-aliasfile does not exist. Instead
I want to have it look into /etc/aliases if the lookup into
/etc/alias.$domain
failed, whether the file did not exist or did not yield a corresponding
alias - I don't (want to) care ;)
Could anyone point me to a direction of how to realize that?
Is it possible to nest the data= of my router even more, as in
doing more checks when the "if exists" fails?
regards
sash
