----------------------------------------
Summary: Mail with multiple recipients get sent multiple times
Key: GERONIMO-6713
URL: https://issues.apache.org/jira/browse/GERONIMO-6713
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: mail, specs
Reporter: Alexander Falb
When sending a mail with javamail to multiple recipients, the mail is sent
multiple times with only one recipient each.
h2. Steps to reproduce:
Setup a project with following dependencies:
{noformat}
org.apache.geronimo.specs:geronimo-javamail_1.4_spec:1.7.1
org.apache.geronimo.javamail:geronimo-javamail_1.4_mail:1.8.4
{noformat}
Call JavaMail:
{code:java}
Properties props = new Properties();
props.setProperty("mail.smtp.host", "localhost");
props.setProperty("mail.smtp.port", "1025");
Session session = Session.getInstance(props);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(Message.RecipientType.TO, new InternetAddress[] {new
InternetAddress("[email protected]"), new InternetAddress("[email protected]")});
message.setSubject("Test Subject");
message.setText("Some Mail Content");
Transport.send(message);
{code}
h2. Actual Result (SMTP log):
{noformat}
SMTP connection from 127.0.0.1/127.0.0.1, new connection count: 1
Server: 220 localhost.local ESMTP SubEthaSMTP null
Client: EHLO localhost

250-AUTH LOGIN
250 Ok
Client: MAIL FROM: <[email protected]>

Server: 250 Ok
Client: DATA
Server: 354 End data with <CR><LF>.<CR><LF>
Server: 250 Ok
Client: QUIT
Server: 221 Bye

h2. Comments:
I use [https://github.com/Nilhcem/FakeSMTP] to record the SMTP log.
Unfortunately the server strips the actual content of the message from the log.
It would be between each "Server: 354 End data with <CR><LF>.<CR><LF>" and
"Server: 250 Ok".
The expected result is produced with {{javax:javaee-api:7.0}} instead of the
above mentioned {{org.apache.geronimo.*}} dependencies.
I'm not 100% familiar with the allowed SMTP command sequences, but I would
suspect sending a message to 2 recipients should not result in sending the
entire message body twice over the wire with only one recipient each?
I tracked the problem down to Transport#send(Message message, Address[]
addresses). This method groups recipients by Transport. The problem is 2
Transports are never the same, because Session#getTransport(..) uses internally
Session#getSerivce(Provider provder, URLName name) which in turn instantiates a
new Transport Object for each call. So the final Transport-to-Address Map looks
like this: \{SMTPTransport->[[email protected]], SMTPTransport->[[email protected]]}
javax:javaee-api:7.0 works around this, by grouping by an
Transportidentifierstring "rfc822", which a map like this: \{"rfc822":
[[email protected], [email protected]]}
I tried upgrading to the latest versions of {{org.apache.geronimo.*}} with no
success.
