97.5 Preventing the GWIA from Acting as a Relay Host

Use the GWIA --disallowauthrelay switch to prevent spammers from using GroupWise accounts to authenticate to the GWIA and then using it as a relay host for their spam. The switch has no effect on normal GroupWise account usage in the GroupWise client or WebAccess. However, it does prevent users who access their GroupWise mailboxes from a POP or IMAP client from sending messages to users outside of the GroupWise system, because the GWIA identifies this activity as relaying.
