New Features in Exim
--------------------
------------
1. ACL variables can now be given arbitrary names, as long as they start with
- "acl_c" or "acl_m" (for connection variables and message variables) and are
- at least 6 characters long. However, only alphanumeric characters and
- underscores are allowed. This is a compatible change because the old set of
+ "acl_c" or "acl_m" (for connection variables and message variables), are
+ at least six characters long, with the sixth character being either a digit
+ or an underscore. The rest of the name can contain alphanumeric characters
+ and underscores. This is a compatible change because the old set of
variables such as acl_m12 are a subset of the allowed names. There may now
be any number of ACL variables. For example:
- set acl_c_foo = something
- set acl_ccc = thingsome
- set acl_m13 = value for original ACL variable
- set acl_m13b = whatever
+ set acl_c13 = value for original ACL variable
+ set acl_c13b = whatever
+ set acl_m_foo = something
- What happens if an undefined ACL variable is referenced depends on the
- setting of the strict_acl_vars option. If it is false (the default), an
- empty string is substituted; if it is true, an error is generated. This
- affects all ACL variables, including the "old" ones such as acl_c4.
- (Previously there wasn't the concept of an undefined ACL variable.)
+ What happens if a syntactically valid but undefined ACL variable is
+ referenced depends on the setting of the strict_acl_vars option. If it is
+ false (the default), an empty string is substituted; if it is true, an error
+ is generated. This affects all ACL variables, including the "old" ones such
+ as acl_c4. (Previously there wasn't the concept of an undefined ACL
+ variable.)
The implementation has been done in such a way that spool files containing
ACL variable settings written by previous releases of Exim are compatible
used, spool files written by the new release can be read by earlier
releases.
+2. There is a new ACL modifier called log_reject_target. It makes it possible
+ to specify which logs are used for messages about ACL rejections. Its
+ argument is a list of words which can be "main", "reject", or "panic". The
+ default is "main:reject". The list may be empty, in which case a rejection
+ is not logged at all. For example, this ACL fragment writes no logging
+ information when access is denied:
+
+ deny <some conditions>
+ log_reject_target =
+
+ The modifier can be used in SMTP and non-SMTP ACLs. It applies to both
+ permanent and temporary rejections.
+
+3. There is a new authenticator called "dovecot". This is an interface to the
+ authentication facility of the Dovecot POP/IMAP server, which can support a
+ number of authentication methods. If you are using Dovecot to authenticate
+ POP/IMAP clients, it might be helpful to use the same mechanisms for SMTP
+ authentication. This is a server authenticator only. The only option is
+ server_socket, which must specify the socket which is the interface to
+ Dovecot authentication. The public_name option must specify an
+ authentication mechanism that Dovecot is configured to support. You can have
+ several authenticators for different mechanisms. For example:
+
+ dovecot_plain:
+ driver = dovecot
+ public_name = PLAIN
+ server_name = /var/run/dovecot/auth-client
+ server_setid = $auth1
+
+ dovecot_ntlm:
+ driver = dovecot
+ public_name = NTLM
+ server_name = /var/run/dovecot/auth-client
+ server_setid = $auth1
+
+4. The variable $message_headers_raw provides a concatenation of all the
+ messages's headers without any decoding. This is in contrast to
+ $message_headers, which does RFC2047 encoding on the header contents.
