Sendmail tells the world it's version..

[mufka]

Is there a way in Sendmail 8.9.3 to keep it from advertising it's version
when someone telnets to port 25?

From left field: can you make it not respond to telnet on port 25 without a
firewall? And without killing SMTP?

Qpopper has a great feature --enable-shy, does sendmail?

Thanks

I dont remember it offhand, but go thru /etc/sendmail.cf and you will see that message format in there. Make sure that you keep a copy of original before modifying.

There might be a m4 macro also to do this.

Here's the config line.
