When SmartPOP2Exchange needs more time than the interval allows that account will be directly process next turn again.
Youalso enter the max. messages to be downloaded from one account duringone turn. If three are more messages on to be downloaded as this max.value SmartPOP2Exchange will half the interval of this account for the next turn.
The download of mails SmartPOP2Exchange does is not parallel. So there will be not duplicate downloading of mails.
There are 3 accounts:
- Max messages: 10
1. account1 with interval 180 seconds
2. acoount2 with interval 60 seconds
3. account3 with interval 270 seconds
Account1: 5 mails
--time needed 10 seconds
Account2: 10 mails
--time needed 20 seconds
Account3: no mails
--time needed 2 seconds
Wait 38 seconds
Account1: not in schedule (127 left)
Account2: 15 Mails --> process 10 --> set interval to 30
--time needed 20 seconds
Account3: not in schedule (197 left)
Wait 10 seconds
Account1: not in schedule ( 97 left)
Account2: 6 mails
--time needed 15 seconds
Account3: not in schedule (172 left)
This sounds like you entered the wrong server in the SMTP settings of SmartPOP2Exchange.
The server to be entered there is NOT the SMTP of your provider (this would create a loop). It 's the receiving SMTP/Exchange Server of your local network.
No. As there does no standard exist for handling catch-all account every nearly providerhas a different behavior on its pop3/imap catch-all accounts.
So SmartPOP2Exchange is implemented to work with most providers.For getting the destination address in your AD SmartPOP2Exchange needs to parse the header fields of each mail it downloads from the pop3 catch-all account.
Therefore it examines the following headers:[ 'Received: ' ... 'for ']
[ 'X-ORIGINAL-To ']
[ 'envelopeaddress ']
[ 'X-Envelope-To ']
[ 'Envelope-To ']
[ 'delivered-To ']
[ 'RCPT-To ']
[ 'X-RCPT-TO ']
[ 'X-RECIPIENT ']
[ 'X-APPARENTLY-TO ']
[ 'X-ORIGINALLY-To ']
[ 'ORIGINAL-RECIPIENT ']
Depending on the server your mail was sent through its headers are different. Additionally your catch-all account provider adds headers to the mail.
These headers are very often wrong. (e.g. some add the name of the catch-all pop3account as X-original-to address)
In general we recommend not to use catch-all accounts as there are some constellations where mail gets lost which can 't be fixed with any pop3-connector.(BCC recipients)
Yes. SmartPOP2Exchangeuses the SMTP protocol to communicate with the SMTP/Exchange Server. So itmakes no difference installing SmartPOP2Exchange on the same machine like yourSMTP/Exchange Server or another machine as long as there is nothing in-between blocking the SMTP port.
The SmartPOP2Exchange itself does not use much CPU but the included SpamAssassin does.
The CPU usage also depends on how much mails are processed (max mails setting) and how big your message are.
