The mailing list for listmasters using Sympa

["christopher pax" <address@concealed>]

My sympa system was working fine a month ago. then i took a break from
it. and now that im starting to work on it again, all of my list do
not seem to work.

whats weird, is there are not errors in the maillog or sympa.log.
i tried emailing to the list from the web; no luck.
then i tried to mail to a list from my email account; no luck.

i used the log files to localize the problem, but could not see where
it is failing.

can any of you give me some troubleshooting set of steps to help me
find the problem.
