Here's a maillog entry that's one of many I receive when I try sending a test message to my system. The recipient is a virtual user in /etc/virtual. The way I'm expecting it to work is that my message from me to this Postfix virtual user will be sent back to me. Every time the message delivery is attempted, Dovecot says the LMTP directory doesn't exist. I thought it was created automatically as messages arrive.

Jun 18 01:48:27 <machine-name> postfix/lmtp[30644]: 4CA5B8CB6: to=, orig_to=<postmaster>, relay=none, delay=0.02, delays=0.02/0/0/0, dsn=4.4.1, status=deferred (connect to <my-FQDN>[private/dovecot-lmtp]: No such file or directory)

I think "private/dovecot-lmtp" isn't found. Please compare your Dovecot socket configuration and Postfix-main.cf configuration to http://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP

(The group may not be "postfix" for your system.)

service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } }

virtual_transport = lmtp:unix:private/dovecot-lmtp
