>Description:
Turned on sysctl log-in-vain knob on firewall/sendmail gateway machine. Every time I use the build in 'mail' command to create and send an email to to another user on local LAN domain name, log-in-vain issues these messages. Logged in as root sending email to root also produces same results. 
Connection attempt to TCP 127.0.0.1:113 from 127.0.0.1:1034 flags:0x02
Connection attempt to TCP 127.0.0.1:113 from 127.0.0.1:1034 flags:0x02
Connection attempt to UDP 127.0.0.1:512 from 127.0.0.1:1047

Also get
Connection attempt to UDP 127.0.0.1:512 from 127.0.0.1:1047
message when Lan user connects to qpopper to retrive their mail.



     
>How-To-Repeat:
turn on log-in-vail knob. uses 'mail' command to send root an message.  
>Fix:
    Change log-in-vain code to let this condition pass as valid and not issue message.
