I have a problem with content file. as you see in attachment;
emailrelay logs and envelope fileshave right RCPT and TO addresses. but in content file To field is missing.
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 like it has been corrupted, so I think the message is just being sent with an empty To: header. A network trace from wireshark, tcpdump or similar should be able to confirm.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
its just a simple one mail example to see To addresses missing. In prod, I use network filter for address validation and content filter. but same result.
anyway, in log file these lines show me that SMTP client send TO address and its seems ok. but in content file To is empty;
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.

Oh, I see. now I get it.
Many thanks!
