Hi everybody. I am hoping someone can help me with a problem I have with Postfix (v2.3.3) and Cyrus (v2.3.7-Invoca-RPM-2.3.7-1.1.el5) running on RHEL5.1. We are trying to migrate from a Debian Sarge system to the RHEL5.1 server. There seems to be a problem when cyrus/lmtpunix gets a mail and tries to save it to a mailbox. I get the following error in maillog: May 15 10:49:05 mail1 lmtpunix[25257]: verify_user(user.username) failed: Mailbox does not exist. I will include a longer paste further down. I have created the mailbox with cyradm. [root@mail1]# cyradm localhost IMAP Password: localhost.localdomain> lm username (\HasNoChildren) root (\HasNoChildren) user^username (\HasNoChildren) user^root (\HasNoChildren) userusername (\HasNoChildren) userroot (\HasNoChildren) localhost.localdomain> I am probably missing something obvious but I can't for the life of me understand what. We are using multiple domains in postfix which seems to work fine as the correct username is forwarded to the lmtpunix daemon. /var/log/maillog May 15 10:48:56 mail1 postfix/smtpd[25246]: connect from localhost.localdomain[127.0.0.1] May 15 10:48:56 mail1 postfix/smtpd[25246]: lost connection after CONNECT from localhost.localdomain[127.0.0.1] May 15 10:48:56 mail1 postfix/smtpd[25246]: disconnect from localhost.localdomain[127.0.0.1] May 15 10:49:05 mail1 postfix/smtpd[25246]: connect from localhost.localdomain[127.0.0.1] May 15 10:49:05 mail1 postfix/smtpd[25246]: C5EC750083: client=localhost.localdomain[127.0.0.1] May 15 10:49:05 mail1 postfix/cleanup[25266]: C5EC750083: message-id=<20080515084905.C5EC750083@xxxxxxxxxxxx> May 15 10:49:05 mail1 postfix/qmgr[25226]: C5EC750083: from=<user@xxxxxxxxxx>, size=379, nrcpt=1 (queue active) May 15 10:49:05 mail1 postfix/smtpd[25246]: disconnect from localhost.localdomain[127.0.0.1] May 15 10:49:05 mail1 lmtpunix[25257]: accepted connection May 15 10:49:05 mail1 lmtpunix[25257]: lmtp connection preauth'd as postman May 15 10:49:05 mail1 lmtpunix[25257]: verify_user(user.username) failed: Mailbox does not exist May 15 10:49:05 mail1 master[25268]: about to exec /usr/lib/cyrus-imapd/lmtpd May 15 10:49:05 mail1 lmtpunix[25268]: executed May 15 10:49:05 mail1 postfix/lmtp[25267]: C5EC750083: to=<username@xxxxxxxxxxxx >, orig_to=<username@domain1>, relay=mail.domain1[/var/lib/imap/socket/lmtp], delay=0.12, delays=0.05/0.02/0/0.04, dsn=5.1.1, status=bounced (host mail.domain[/var/lib/imap/socket/lmtp] said: 550-Mailbox unknown.
