The smtp2pop3 cannot really identify a slow connection versus a down connection. One cycle it send the email and the next cycle (depending on your configuration) it receives it. If it does not receive the appropriate mail (sequence number if you will) then it is down. Now you can control how often it checks by using the check priority in Server's Alive. This allows you to get a around a slow connection.
I envision setting up a couple of SMTP2Pop3 checks checking on different cycles. For example your first one checks every cycle. The other one checks every 5 cycles (~5-10 minute if Salive is set to check every minute) and therefore will be down only if emails take longer than 5 minutes to travel end-to-end. Yet another check that runs every 20 or more cycles. When one is down you know it is slow when all three down you know it is really down. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tim Sent: Wednesday, November 03, 2004 3:11 PM To: [EMAIL PROTECTED] Subject: [SA-list] SMTP2POP3 check (mailflow) Can someone explain to me exactly what this SMTP2POP3 mail flow check is actually checking? I know in general it sends an email using SMTP and then checks if it is in the mailbox via POP3. Does it use sequence numbers to determine if a mail is lost? For example, it sends email #1, email #2 and on check it only ever gets #2. In this case is a DOWN reported (ie. email #1 has been lost but mail is actually flowing in a limited way)? Can it determine that there is a long email delay. That is, mail is flowing but its taking 10 mins, 2 hours to get from SMTP to POP3?? Basically I need to determine these two cases not just mail flow so I need to know that this tool can determine this. If it cannot, is there anything else out there that I can use or any suggestions on what one would need to do to put this together using SA?
