<br><br><br> How do you manage concurrent connections in Sendmail? I know<br>about confCONNECTION_RATE_THROTTLE and WINDOW_SIZE but is there<br>anything that will limit the number of concurrent connections from a<br>
single IP address?<br><br> -Vlad<br><br><br> On 8/31/07, Gareth <<a href="mailto:list-mailscanner@linguaphone.com">list-mailscanner@linguaphone.com</a>> wrote:<br><br> cat /var/log/maillog | grep -E "(connection
