-------------------------------------
Summary: RSET do not impact ESMTP ID in Received header
Key: JAMES-3648
URL: https://issues.apache.org/jira/browse/JAMES-3648
Project: James Server
Issue Type: Bug
Components: SMTPServer
Affects Versions: 3.6.0
Reporter: Benoit Tellier
The ESMTP ID is correlated to the channel number thus sending two mails with a
RSET in between result in the same ESMTP ID in the received log.
Here is such an example using telnet:
{code:java}
$ telnet 172.17.0.2 25
Trying 172.17.0.2...
Connected to 172.17.0.2.
Escape character is '^]'.

I do not have at hand specifications and expectations for that ESMTP ID.
We maybe rather look at what Postfix does.
I do not know ifit need to be unique on a per-mail bases.
