I have a virus and spam filter device that can do VRFY commands to reject invalid email before it gets to the next mail hop. How can I configure the SMTP server to only allow VRFY commands from one particular IP address, and nowhere else? I don't want spammers to be able to hammer on the gateway looking for valid addresses to send to.

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm is installed for auth PLAIN It reports this from the EHLO so all looks good: 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLA...
