virtusertable : 특정 이메일 주소로 받은 메일을 다른 사용자에게 할당할때 사용

[root@server1 ~]# find / -name virtusertable
/etc/mail/virtusertable

 

[root@server1 ~]# vi /etc/mail/virtusertable

# A domain-specific form of aliasing, allowing multiple virtual domains to be
# hosted on one machine.
#
# info@foo.com  foo-info
# info@bar.com  bar-info
# joe@bar.com   error:nouser 550 No such user here
# jax@bar.com   error:5.7.0:550 Address invalid
# @baz.org      jane@example.net
#
# then mail addressed to info@foo.com will be sent to the address foo-info,
# mail addressed to info@bar.com will be delivered to bar-info, and mail
# addressed to anyone at baz.org  will be sent to jane@example.net, mail to
# joe@bar.com will be rejected with the specified error message, and mail to
# jax@bar.com will also have a RFC 1893  compliant error code 5.7.0.
#
# The username from the original address is passed as %1 allowing:
#
# @foo.org      %1@example.com
#
# Additionally, if the local part consists of "user+detail" then "detail" is
# passed as %2 and "+detail" is passed as %3  when a match against user+* is
# attempted, so entries like
#
# old+*@foo.org new+%2@example.com
# gen+*@foo.org %2@example.com
# +*@foo.org    %1%3@example.com
# X++@foo.org   Z%3@example.com
# @bar.org      %1%3
#
# Note: to preserve "+detail" for a default case (@domain) %1%3 must be used
# as RHS. There are two wildcards after "+": "+" matches only a non-empty
# detail, "*" matches also empty details, e.g., user+@foo.org  matches#
# +*@foo.org but not ++@foo.org. This can be used to ensure that the
# parameters %2 and %3 are not empty.
#
# All the host names on the left hand side (foo.com, bar.com, and baz.org)
# must be in class {w} or class {VirtHost}. The latter can be defined by the
# macros VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE (analogously to
# MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE). If VIRTUSER_DOMAIN or
# VIRTUSER_DOMAIN_FILE is used, then the entries of class {VirtHost} are
# added to class {R}, i.e., relaying is allowed to (and from) those domains.
