During the rewriting process, all registered headers containing addresses must be parsed in order to rewrite and eliminate shortform addresses and otherwise convert them to legal addresses. During this process personal names (strings preceding angle-bracket-delimited addresses) are extracted and can be optionally modified or excluded when the header line is rebuilt.
This behavior is controlled by the use of the personalinc, personalomit, and personalstrip keywords. personalinc tells IMTA to retain personal names in the headers. It is the default. personalomit tells IMTA to remove all personal names. personalstrip tells IMTA to strip any nonatomic characters from all personal name fields. These keywords can be applied to any channel.
