--------------------------------------------
Summary: Add Restart Save Mail-Queue
Key: OPENMEETINGS-327
URL: https://issues.apache.org/jira/browse/OPENMEETINGS-327
Project: Openmeetings
Issue Type: Bug
Affects Versions: 2.0 Apache Incubator Release
Reporter: SebastianWagner
Fix For: 2.1 Apache Incubator Release
Currently mails are send "In-Context". Normally in a separated Thread.
But there is no control about the number of Threads, which can lead to problems
if the server is under heavy load.
Also if you terminate the service while runnning and restart Mails that where
currently in progress are just gone.
To have better control about it there should be some kind of queueing for the
Mails to be processed.
To do that one approach would be:
Create a new table "mail_queue" [Fields: id, subject, receipents(can be comma
separated list), message, sendStatus, errorMessage, starttime, updatetime].
Every time the system wants to send a new mail it will write a new entry in
this table.
A separated scheduler will check every xx seconds for entries in that table /
open emails that need to be send and will process them.
Processes emails can be:
- Either deleted from the table
- Or maybe better jsut update the sendStatus and delete them via the
Administration by user on demand to have a chance to look at possible issues
and errors.
The MailHandler should write problems and errors when sending emails to the
error field.
Bonus: Would be great if you can see the current Mail-Queue in the
Administration panel and change the sendStatus to provoke resending it.
