Alias tag alias option

Tag inserted on Subject: header line alias option:  (string)
The  alias option  may be used to prefix specified text to the  Subject: header of posted messages. The   should be the string to be added. The string should not contain the vertical bar, , character; prior to MS 6.3, the  string should not have contained the space character. For instance, msconfig&#x3e; set alias:schedule-list@domain\.com.alias_tag "Schedule posting -- " msconfig# show alias:schedule-list@domain\.com instance.alias:schedule-list@domain\.com.alias_entry = "&#x3c;ldap:///o=usergroup?mail?sub?(isMember=schedule-list)" instance.alias:schedule-list@domain\.com.alias_auth_list = "&#x3c;ldap:///o=usergroup?mail?sub?(isMember=schedule-list)" instance.alias:schedule-list@domain\.com.alias_tag = "Schedule posting -- " will cause any postings to the list schedule-list to have a Subject: header that begins " " followed by whatever the  original subject of the posting might have been. See the   MTA option  for setting an attribute name to provide  analogous functionality for lists defined in LDAP, and in legacy configuration, see instead the alias file named parameter.
