I am having a bit of a problem with error mail getting to the owner of a list. The owner field of the list looks like Owner= [log in to unmask] However, when error mail gets created to be sent to the owner, the address gets translated to [log in to unmask] The problem is that foo.bar is an IBM workstation running AIX 3.1, and the userid is in lowercase; when mail for the user comes in with the userid in uppercase, it gets bounced because there is no userid of USER (uppercase userid). AIX is keeping the userid uniquely lowercase (correct behavior). Question: is there any way to have LISTSERV preserve the case of the userid that the error mail is being sent to? Any help or suggestions would be appreciated. Rich PS. I am running 1.7b, VM/XA 2.1, and MAILER 2.08.
