Subject: How Long to Respond to HELO?

In examining logs generated while trying to figure out why dnsreport.com could not contact my mail servers, I got to wondering why SIMS takes so long to respond to HELO. From one of my server logs:

14:54:03 4 SMTP-698([24.240.171.218]) Input Line: HELO dnsreport.com\r
14:54:03 5 SMTP-698([24.240.171.218]) *Status=21
14:54:03 4 SMTP-698(dnsreport.com) Looking for dnsreport.com
14:54:18 3 SMTP-698(dnsreport.com) Failed to verify. Real address is [24.240.171.218:3884]
14:54:18 4 SMTP-698(dnsreport.com) Sending 250 SMTP.az.net cannot verify dnsreport.com\r\n


And from the other:

14:35:17 4 SMTP-212([24.240.171.218]) Input Line: HELO dnsreport.com\r
14:35:17 4 SMTP-212(dnsreport.com) Looking for dnsreport.com
14:35:47 3 SMTP-212(dnsreport.com) Failed to verify. Real address is [24.240.171.218:4325]
14:35:47 4 SMTP-212(dnsreport.com) Sending 250 MDCCLXXVI.com cannot verify dnsreport.com\r\n

Isn't 15-30 seconds a bit long?
