===== Problem =====
<code>
Apr 15 03:33:35 server1 postfix/lmtp[5957]: E646F20437: to=<bob@example.com>, relay=none, delay=0.03, delays=0.03/0/0/0, dsn=4.4.1, status=deferred (connect to mail1.example.com[/var/run/cyrus/socket/lmtp]: No such file or directory)
</code>

===== Solution =====
//postfix// try to transport the mail to the MDA via LMTP via socket, but //postfix// runs in a chroot and has no chance to access the LMTP socket. Set the lmtp component to run not in chroot:

<code|/etc/postfix/master.cf>
-lmtp      unix  -       -       -       -       -       lmtp
+lmtp      unix  -       -       -       -       -       lmtp
