Understandable.

On another note, I’ve noted via the same parse that this in exim.conf:

-----
router_home_directory = ${extract{5}{::}{${lookup{${lookup{$domain_data}lsearch{/etc/userdomains}{$value}}}lsearch{/etc/passwd}{$value}}}}
-----

… gets parsed to this:

-------
router_home_directory = ${extract{5}{::}{${lookup passwd{${lookup{$domain_data}lsearch{/etc/userdomains}{$value}}}{$value}}}}
-------

^^ Note the conversion of the first “lookup” to a “lookup passwd”.

But, if I reflow the exim.conf a bit to:

-----
    router_home_directory = ${extract \
        {5} \
        {::} \
        {${lookup \
            {${lookup \
                {$domain_data} \
                lsearch \
                {/etc/userdomains} \
                {$value} \
            }} \
            lsearch {/etc/passwd} \
            {$value} \
        } } \
    }
-----


… then the conversion to “lookup passwd” doesn’t happen:

-----
router_home_directory = ${extract {5} {::} {${lookup {${lookup {$domain_data} lsearch {/etc/userdomains} {$value} }} lsearch{/etc/passwd} {$value} } } }
-----

Is this an optimization of some kind in Exim, which the breaking up into multiple lines is losing?

Thank you!
