This error message is reported by the Exchange Server to SmartPOP2Exchange when SmartPOP2Exchange tries to sent the mail to the Exchange Server.The Exchange Server 2007 needs much resources (like 2GB RAM etc.) especially if you haven 't installed the SP1 the ExchangeServer 2007 requires 4GB free disk space:See https://exchangepedia.com/blog/2008/02/exchange-server-2007-sp1-most-obscure.html
No. SmartPOP2Exchange is designed to forward mails from POP3/IMAP accounts to any SMTP/Exchange Server. As SmartPOP2Exchange does use the SMTP protocol for this it does not have direct access to the SMTP/Exchange Server. - It 's unidirectional.
There is no special order required.
Simply export your data (account name, SMTP address[recipient], pop3/imap server, pop3/imapusername, pop3/imap password, imap mailbox) and start the import wizard of SmartPOP2Exchange.
The wizard will open your file and then you can assign the columns to the appropriate value.
The service of SmartPOP2Exchange (SmartPOP2SMTP.exe) needs about 20-50MB memory depending on how much messages are processed and how big they are. But if you use the integrated ClamAV it needs about 120 MB minimum additionally. So theservice of SmartPOP2Exchange may take up to 200-300 MB memory.
You may run SmartPOP2Exchange on a different machine.
Yes, SmartPOP2Exchange logs the message ID of successful delivered mails. So if you like mails to be delivered again you need to use the button "Reset history of successful delivered mails". But take care: all mails will be downloaded again depending on the setting "Download messages marked as 'read '".
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.
Example:
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
Start...
Account1: 5 mails
--time needed 10 seconds
Account2: 10 mails
--time needed 20 seconds
Account3: no mails
--time needed 2 seconds
#next turn
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)
#next turn
Wait 10 seconds
Account1: not in schedule ( 97 left)
Account2: 6 mails
--time needed 15 seconds
Account3: not in schedule (172 left)
#Next turn
....
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. SmartPOP2Exchange uses the SMTP protocol to communicate with the SMTP/Exchange Server. So it makes no difference installing SmartPOP2Exchange on the same machine like your SMTP/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.
