qmgr

sendmail
Postfix core program that reports postfix queue stats
showq
Postfix core program that forwards messages to external hosts using SMTP
smtp
Postfix core program that receives messages from external hosts using SMTP
smtpd
Postfix core program that retrieves messages from cleanup and ensures the header is in a standard format for qmgr and is used by qmgr to resolve remote host addresses
trivial-rewrite
Postfix utility program that checks the postfix mail queue for messages and displays the results

postfix
Postfix utility program that creates, updates or queries the alias dtabase
postalias

postcat
Postfix utility program that sends commands to running postfix services
postkick
Postfix utility program that locks specified postfix files and executes specified commands
postlock
Postfix utility program that logs to the system-logging facility
postlog
Postfix utility program that creates or queries a postfix lookup table
postmap
Postfix utility program that performs maintenance on specified postfix queue directories
postsuper
Location for postfix config files
/etc/postfix/
Postfix configuration file that contains info from the install parameters used when postfix was installed
install.cf
Postfix configuration file that contains parameters used by the postfix programs when processing messages
main.cf
Postfix configuration file that contains parameters used by the postfix master program when running core programs
master.cf
Common postfix config setting that defines the hostname of the server
myhostname
e.g. myhostname = mailserver.smallorg.org
Common postfix config setting that defines the domain name of the server
mydomain
e.g mydomain = smallorg.org
Common postfix config setting that specifies the domain or hostname to be used for outgoing messages
myorigin
e.g. myorigin = smallorg.org
Common postfix config setting that specifies domain(s) postfix will accept mail for
mydestination
e.g. mydestination = smallorg.org, mediumorg.org
Common postfix config setting that specifies domains that are allowed to forward mail on this postfix server
relay_domains
e.g. relay_domains = bigorg.org
Common postfix config setting that defines another SMTP server for all outbound messages
relayhost
e.g. relayhost = mx1.myisp.com
Common postfix config setting that specifies a file that maps domain aliases to user accounts
virtual_alias_domains
postfix lookup table that maps remote hosts to accept or deny table for security
access
postfix lookup table that maps recipients to local mailboxes
alias
postfix lookup table that maps alternative mailbox names to real mailbox names
canonical
postfix lookup table that old user mailbox names to new mailbo name
reloacted
postfix lookup table that maps domain names to delivery methods
transport
postfix lookup table that maps recipients an domains to local mailboxes
virtual
postfix security setting that enables TLS
smtpd_tls_security_level
e.g. smptd_tls_security_level = may
postfix security setting that specifies the TLS certificate file for the postfix server
smtpd_tls_cert_file
e.g. smptd_tls_cert_file = /etc/postfix/cert.pem
postfix security setting that specifies the TLS certificate key file for the postfix server
smtpd_tls_key_file
e.g. smtpd_tls_key_file = /etc/postfix/key.pem
