Can someone explain to me why our e-mail addresses are not correctly interpreted by Listserver Version: 6.0 -- Unix ListServer by Anastasios Kotsikonas? We run VM with Music/SP as guest and use Columbia Network Mailer with SMTP. Our Music users' addresses, [log in to unmask], are being interpreted as [log in to unmask] Our CMS users are [log in to unmask] The Music userids do not exist in the CP directory, so all the undeliverable mail piles up on the SMTP postmaster account. Do we have a configuration problem or is the problem with Unix ListServer? I would appreciate any explanation. Helen P.
