Unable to send mail via postfix. Messages get stuck in queue:

Postfix actively uses hostname getting from OS. As described at

Postfix tries to get domain name by gethostname() posix call. But gethostname() checks FQDN hostname and returns error (the same error in newaliases output). As result postfix couldn't process e-mails in qmgr because of FQDN hostname used as a default value for many other configuration parameters.


Set correct hostname like in:

#vi /etc/hostname
#vi /etc/hosts
