I hit this last week, ended up running 'strings' on the lsv binary. ;)

It seems to be as follows:

MAILER@* *DAEMON*@* *POSTMASTER@* *MAISER*@* NETWORK_MANAGER@* ADMINISTRATOR*@*
GATEWAY*@* MAILOP@* POST*OFFICE@* *@SELL.COM *@*.SELL.COM [log in to unmask]
[ANONYMOUS]@* *@*.DJSA.COM *@DJSA.COM *MAJORDOM*@* *@*FINDMAIL.COM IMAILSRV@*
*@WEBCLIPPING.COM *@*.WEBCLIPPING.COM *@*.GACRACKER.ORG *@EWATCH.COM
*@SUITES.COM

(fun and games - a user had a legitimate userid 'gateway@' and hilarity ensued)
