do the PIXs always change the banner to all asterisks except for /[20 ]/ ?
i originally suspected a PIX for the Mercury problem i just posted, but
the banner just says:
# telnet n.n.n.n 25
Connected to n.n.n.n.
Escape character is '^]'.
220 SMTP service ready
250-Requested mail action okay, completed
221 SMTP server closing transmission channel
it looks like they're running some kind of firewall because queso says:
# queso n.n.n.n:25
n.n.n.n:25 *- Unknown OS, pleez update /etc/queso.conf
