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.

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.

The unlimited version of SmartPOP2Exchange is not limited in the number of accounts or users.

The reason is simple: BCC recipients (Blind Carbon Copy) are not listed in the mail message. Therefore, there is no way to identify BCC recipients by analyzing the email content. BCC stands for "Blind Carbon Copy," meaning that recipients in the BCC field are invisible to other recipients of the mail.

The interval on the "Settings" and on the "Schedule" tab is the same. If you change one that other one will change too.
So this are just two places where you can modify the same value.

Just substitute the "INBOX" text in the IMAP settings of "Mailbox" by the name of the desired folder. You can also use "INBOX/subfolder" or "INBOX\subfolder" (depending on your provider) for retrieving messages from subfolders.
