Yes, of course. Thank you ahmad. I no longer get the literals passing through the filter, but my variables still are not being interpolated. Now I am seeing:

    \textbf{} & box & :  &   &  \\
    \hline

    \hline

    \textbf{} & box & :  &   &  \\

where my template now reads:

[% FOREACH recipient IN call_list %]
    \textbf{[% recipient.email %]} & box & [% recipient.uid %]: [% rec
+ipient.name %] & [% recipient.fname %] [% recipient.lname %] & [% rec
+ip
ient.phones %] \\
    \hline
    [% FOREACH sponsor IN call_list.recipient.upstream %]
        \multicolumn{2}{||r|}{[% sponsor.email %]} & [% sponsor.uid %]
+: [% sponsor.name %] & [% sponsor.fname %] [% sponsor.lname %] & [% s
+po
nsor.phones %] \\
    [% END %]
    \hline
[% END %]
