However, if we stop cyrus-imapd for whatever reason without stopping sendmail first, we end up in a situation where the lmtpd gets stuck upon a restart of cyrus-imapd. To be precise, it doesn't accept connections from sendmail and if we strace it all we see is:accept(4, That's it. The workaround then is to stop both sendmail and cyrus-imapd and to wait for several minutes. After that, if we start the processes in the right order, everything is fine again. Is this behavior to be expected or is it a bug?I'd call it a bug offhand, but there are possibly other things going on. Do all the previous lmtpds die off before you restart cyrus?
Yes, they do.
I used socat instead:Can you make a connection to the new lmtpd socket manualy (if it's a unix socket, you may want to try sock, from ftp://atrey.karlin.mff.cuni.cz/pub/local/mj/linux/sock-*.tar.gz).
socat STDIN UNIX-CONNECT:/var/lib/imap/socket/lmtp

I found that (at least this time) I *could* connect to the socket. Then it dawned on me: sendmail didn't even try to deliver to localhost because we are using persistent hoststatus information!
A "rm -f /var/spool/mqueue/.hoststat/localhost" got rid of that problem.
So at least *this* case was an instance of d'oh!

I'll keep that in mind in case of further problems.
