Initially the update had turned off everyone's notification emails 😞 , I then manually turned on my notifications and noticed that it updated the database yaf_user.NotificationType to 30 - so I then did an update query to set all users to this value. Notifications are now on, but everyone is receiving 3 notification emails instead of just one.

Can someone tell me where I'm going wrong, or point me to where I can fix this?

Thanks.

On a lucky day one is sent, most common is 2-3 mails also for forum registrations and such...

Do not think it's an email provider thingy.... Rather a kind of too quick "oops, no contact - better try to send again" type of evaluation in the forum software... Didn't do that with 1.9,4 if I remember correctly.

Well I didn't have this problem in version 1.9.4 RC1 - maybe I can use the notification code from that version?

The issue has been raised before in the forum, but was then "blamed" on ISP mail provider issues.

Maybe it's time to have a little look at the mail sending routine code to see if it needs an overhaul in logic?

so yes today for the first time i got dual mails of a topic i have watched .. so i guess it might happen with others as well .. :S ..will see the mail time and logs if anything matches

My users are getting tired of getting multiple mails for each message posted in watched topics and such...

This issue has been resolved in yaf 1.9.6.1 rtw, it was an issue with the task manager.

Any chance you can be more specific? I'm on v1.9.5.5 and my hosting platform doesn't support .net v4

Thanks.

Almost like it won't clear messages out of the queue unless it's able to complete the whole queue. We're going to go to 1.9.6 soon - I just haven't had the time to deal with it on our site yet --

I have noticed also that since we moved the forums to the new server, it's been sending notifications with no problems and no duplicates. Thera are big differences between the two servers: IIS versions, OS Versions, SQL Versions, and the change in mailserver. We don't use a pickup directory - we just talk to the IIS SMTP on an internal port and that's it. We used to talk to our public mailserver instead.

We did also recently go through the database and disable notifications for messages by default and instructed users how to go and turn them back on if they wanted them. The question is does the queue clear messages one by one if they send or does it process the queue as a 'batch' then clear them if the 'batch' is successful?

Just my notes --

Excellent summary, Squirrel. Thanks for sharing. I hadn't considered the local SMTP environment being an issue, but I have been running YAF on my dedicated server since 2008 and haven't had a single occurrence of multiple emails. And that was with YAF 1.9.3 through to 1.9.6.1. I shouldn't be tempting fate by publicly posting this, but I wanted to add my experience to the pool.

Thanks,

Dave

One thing I have noticed is that my provider server closes the SMTP connection because of time-out after a brief time (120 seconds), while our own server has got a very long time out setting, 15 minutes.

It's on the same server with the same SMTP settings, the only thing that's changed is YAF 😞
