Which database are you using for your fullnames? ZMailer has a built in
one (fullnamemap), separate from aliases. I defined it at our site to be:
z# db toc
...
fullnamemap ndbm 0/10 l /zmailer/db/fullnames
...
I have had no trouble at all using this. The fullnames file is a sorted
2 field file, all lowercase (this IS important! - upper -lower cases in
the search string will match if the db is all lowercase), in a simple
format:
dotted.entry.etc.etc username
i.e. some examples from my domain:
anand.rao.kalvey kalvey
charge.symm.breaking.exp ex121
james.s.mackinnon jmack
lake.louise.winter.institute llwi
standard.cf will have:
# optional: Fullname database: <Full.Name> <login>
if [ -f /zmailer/db/fullnames.pag ]; then
relation -lmt ndbm -f /zmailer/db/fullnames fullnamemap
else
fullnamemap () { return 1 }
fi
( <login> can be ANY entry in the aliases file and could point to other
domains or functions as well)
rrouter.cf should look like:
[^.:](\.[^.])+
if [ $(fullnamemap "$address") ]; then
return $(rrouter $(fullnamemap "$address") "$origaddr" $A)
fi
if [ $(newsgroup "$address") ]; then
return (((usenet - "$address" $A)))
fi
return (((error norealname "$address" $A)))
return (((error nonewsgroup "$address" $A)))
;;
The db is compiled with makendbm:
sort -o fullnames fullnames; makendbm fullnames
and it all "just works" (at least in our production ZMailer - 2.99.10).
A trace on the db :
