---------------------------------
Resolution: Invalid
> 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
> Priority: Major
>
> 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.
