Hi Ludovic, I've traced this a bit further. Here's what I have found: * The notification emails are sent from JIRA. I could see in the flush queue that for a comment I've added to an issue there were 2 emails in the queue (one for myself as I was both the reporter and the assignee and one for the xwiki-commits list). * I checked that the jira email user is correctly subscribed to the xwiki-commit list. Actually I was able to send a test email to the list. Ludovic, could you please check (or tell me how I could check) that the SMTP server on the machine where our JIRA server is hosted is actually sending those mails? I believe it should be possible to turn logging on and check that right? It's possible that the mail headers sent from the test page in jira are not the same as the ones used when a notification happens.
