Before I upgraded to ubuntu lucid I used the twitter client "twidge" to get my updates send to thunderbird. I used postfix and dovecot for that.
When I tried to get the configuration to get to work again, the "test drive" worked just fine. I got the tweets in my inbox in thunderbird. Unfortunately since then, it doesn't work anymore. And I have no clue what could be the problem.
I don't get any error messages. Neither from twidge or cron. Nor from thunderbird concerning the local dovecot account. Tere's a mailbox file in /var/mail as well as in /var/spool/mail. But they stay the same size, so I guess nothing gets there.
"ps axf" showed that everything is actually running.
So what could be the problem?
