There shouldn't be any huge difference in speed, but the 2.5.3dev3 binary from May is not production quality so it might be better to test a 2.6 release candidate: https://sourceforge.net/projects/emailrelay/files/OldFiles/emailrelay-2.6rc1.exe/download https://sourceforge.net/projects/emailrelay/files/OldFiles/emailrelay-textmode-2.6rc1.exe/download Note that the event loop changes only take effect once you reach the 64-handle limit. When it switches over there will be a line in the log file something...

There different 'to' addresses: the envelope-to address is used in the SMTP RCPT-TO command, which you see in the log, whereas the content-to is the To: header in the message content. They can be completely different and in your case the content-to header in your test message appears to be empty.

I don't think this can be a problem with emailrelay. The SMTP dialogue specifies envelope-to and envelope-from addresses but these are independent of the To: and From: headers at the start of the message content. E-MailRelay does not interpret or edit the message content in any way, other than to add a Received line -- whatever it receives over the socket is written straight to the content file. Your log file suggests that you are not doing any filtering, and your message content file does not look...

It should be whatever port the server is listening on. I can't tell from your screenshots what that is. It might be 25 or 587 or something else completely. Try using telnet (eg. "telnet localhost 25" with CTRL-] and "quit" to quit) or netstat ("netstat -an -p TCP").

In that case you will need to configure emailrelay with 127.0.0.1 on the "SMTP client" page, and with the correct port number (probably 25 or 587). (Note that the 'mail.cns...' domain name might resolve to the correct machine but the server is only listening on 127.0.0.1)

Socket binding error

Add Support for forwarding .eml files

I'm glad it's working out for you. The next release of the emailrelay-submit tool should mean you don't have to parse out the recipient's envelope address.
