Thank you for your suggestions! It works now. This was an issue with my configuration of Postfix and Cyrus.
In master.cf, as Magnus suggested: lmtp unix - - n - - lmtp In main.cf: virtual_transport = lmtp:[10.1.1.101]:2003 And in cyrus.conf, according to Robert: lmtp cmd="lmtpd -a" listen="10.1.1.101:2003" prefork=1 I have my SELinux disabled for the moment. Evgeniy
