11.4.2 Repeated Rewrites Template, A%B

The following template format is used for meta-rules that require additional rewriting after application of the rule. After the rule is applied, the entire rewriting process is repeated on the resulting new address. (All other rewrite rule formats cause the rewriting process to terminate after the rule has been applied.)

UserTemplate%DomainTemplate[controls]

Note, however, that while the special A%B form does cause rewriting of the current domain to restart, it is actually just a continuation of the current rewriting process. It does not rewrite the entire process from the beginning. It does not perform the $* pattern when it goes through the second time.

For example, the following rule has the effect of removing all occurrences of the .removable domain from the ends of addresses:

.removable $U%$H

Extreme care must be taken when using these repeating rules; careless use can create a “rules loop.” For this reason meta-rules should only be used when absolutely necessary. Be sure to test meta-rules with the imsimta test -rewrite command. For more information on the test -rewrite command, see the Sun Java System Messaging Server 6.3 Administration Reference.
