Siegfried Goeschl commented on EMAIL-158: ----------------------------------------- Hi Hardik, I looked at the error message {code} The Ehlo options for the client proxy target xxxx:xxxx:xxxx:x:x:xxxx:xxx.xxx.x.xx did not match while setting up proxy for user x...@example.com on inbound session 05D2ACA9F88A9066. The critical non-matching options were <maxSize>. T he non-critical non-matching options were <NONE>. Client proxying will continue. {code} and searched a bit but found no definitive answer * What SMTP server is being used? * Can you send an email having the system property "mail.debug" set to "true". Then you should see the SMTP exchange between client & server which could provide some insight > Seeing EHLO option warnings > --------------------------- > > Key: EMAIL-158 > URL: https://issues.apache.org/jira/browse/EMAIL-158 > Project: Commons Email > Issue Type: Bug > Affects Versions: 1.4 > Environment: Ubuntu 14.01 64 bit. > Reporter: Hardik Vohra > > The exchange server is throwing the following error while sending email using > apache commons email library. > ``` > {noformat} > The Ehlo options for the client proxy target > xxxx:xxxx:xxxx:x:x:xxxx:xxx.xxx.x.xx did not match while setting up proxy for > user x...@example.com on inbound session 05D2ACA9F88A9066.
