TCP wrapper filter creation

The IMAP, POP, and HTTP services support Allow and Deny filters via options  and  ; (such filters may also be created for SMTP services, but will only apply to authenticated SMTP sessions; instead see Mail filtering and access control for discussion of the MTA&#x27;s approaches for controlling access). The MMP and its proxy services, the IMAP Proxy, POP Proxy, and vdomain for specifying Virtual Domain specific controls, instead support a  option.

The  utility is used to create or edit  server level TCP wrapper filters in Unified Configuration; for example: msconfig&#x3e; set imap.domainallowed .siroe.com msconfig&#x3e; set pop.domainnotallowed imap.siroe.com msconfig&#x3e; set mmp.tcpaccess "+imap: siroe.com" Note: Restart the relevant services after making changes to their access filters.

TCP wrapper access filters can also be set at the user level or domain level via LDAP attributes; see the user level   LDAP attribute1 and the domain level   LDAP attribute.

1The MMP and its proxy servers and virtual domains permit renaming of the user level LDAP attribute via their  option. The IMAP, POP, and MSHTTP servers, however, do not support such renaming and expect use of the   user level LDAP attribute.
