A number of users at a remote campus location are having their command files to Listserv rejected because of duplicate "To:" records: + To: <[log in to unmask]> + To: [log in to unmask] This appears to have begun happening in the last month. They are using Pegasus Mail for Windows (v2.52). While awaiting a response from the postmaster at that site, I was wondering if anyone has seen anything similiar before?
