[Pkg-mailman-hackers] Bug#421856: mailman: README.Exim4.Debian fails if there are no virtual domains

[Hans G. Ehrbar]

Package: mailman
Version: 1:2.1.9-7
Severity: normal

If there are no virtual domains, then the line

 condition = ${lookup{$local_part@$domain}lsearch{MAILMAN_HOME/data/virtual-mailman}{1}{0}}

in the mailman router has to be commented out.
Otherwise exim4 issues the following paniclog:

2007-05-01 22:57:39 1Hj6uJ-00051h-Nl failed to expand condition
"${lookup{$local_part@$domain}lsearch{/var/lib/mailman/data/virtual-mailman}{1}{0}}"
for mailman_router router: failed to open
/var/lib/mailman/data/virtual-mailman for linear search: No such file
or directory

While you are at it, the file
README.Exim4.Debian
should probably be gzipped.
