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 :
