+ 5. The redirect router has two new options: forbid_sieve_filter and
+ forbid_exim_filter. When filtering is enabled by allow_filter, these
+ options control which type(s) of filtering are permitted. By default, both
+ Exim and Sieve filters are allowed.
+
+ 6. A new option for callouts makes it possible to set a different (usually
+ smaller) timeout for making the SMTP connection. The keyword is "connect".
+ For example:
+
+ verify = sender/callout=5s,connect=1s
+
+ If not specified, it defaults to the general timeout value.
