I’m interested in resolving this issue. I’m on the devs who coded this mail component. I’ve never experienced your problem though so we need to find a way so that I can reproduce it (or understand the problem but that’s going to be hard). So the way it works is that there are 2 threads running: - prepare thread: its goal is to serialise the messages to be sent on disk. This allows to resend if the mail fails or if XWiki is restarted. It also put the mail to be sent on the send thread queue - send thread: send the mails put on its queue. It’s as if the send thread is not noticing that there are mails to be sent. So we’d need to check if the Send thread is alive. I guess you could check that by sending a SIGQUIT to the JVM and checking the thread dump to find the Mail Sending Thread. One thing you could test is to use the memory listener instead of the DB listener for the mail (so that the mail is sent directly). That’ll confirm that everything is working. You can use the following example: http://extensions.xwiki.org/xwiki/bin/view/Extension/Mail+Sender+API#HExample1:Sendasimpletextemail (Adjust the “to” to point to your mail) Thanks -Vincent > -- > View this message in context: > http://xwiki.475771.n2.nabble.com/Email-Validation-stuck-in-prepare-success-status-tp7602814.html > Sent from the XWiki- Users mailing list archive at Nabble.com.
