I have apparently done something to mess up my test installation, as deliver's attempts to send messages now fail with the following error:
deliver(user@example.com): execv() failed: No such file or directory
In these cases, I have sieve rules trying to send messages. It had been working though, and I've tried going through all the changes I made yesterday (related to dictionary quota debugging) to find what could be wrong, but no luck so far. So, I was hoping for suggestions.
Basically, deliver seems to not know where sendmail is. I have sendmail_path set in dovecot.conf (never changed that), yet when deliver tries to pull the location via deliver_set->sendmail_path, it's just returning an empty string. If I hard-code the location in smtp-client.c, it works again.
Any ideas?
