Alexander Grupe created GERONIMO-6490:
-----------------------------------------
Summary: Unable to configure EHLO/HELO host name via property
“mail.smtp.localhost”
Key: GERONIMO-6490
URL: https://issues.apache.org/jira/browse/GERONIMO-6490
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: mail
Affects Versions: 3.0.1
Environment: any
Reporter: Alexander Grupe
Geronimo Mail seems to use the same JavaMail properties as the original Sun
implementation [1].
Unlike the original implementation, however, the “mail.smtp.localhost” property
cannot be used to specify which host name should be used when issuing a EHLO or
HELO command to the SMTP server.
Instead, the return value of {{InetAddress.getLocalHost().getHostName()}} is
always used, regardless of the value of “mail.smtp.localhost”. (To be exact,
the property is only ever used if {{getHostName()}} returns null, which is very
unlikely to happen.)
The local host name returned by {{InetAddress.getLocalHost().getHostName()}}
should rather be used as a *fallback* value, not as an *override* value.
Otherwise, you can only influence what is sent in the EHLO/HELO command by
changing the JVM environment (e.g. by editing {{/etc/hosts}}).
