smtp issue

By jen0dorf on 22 Jan 2018 at 15:14 UTC

my hoster locked out my drupal site because of excessive email use, so I installed the smtp authentication module and set it up for gmail.

I now am unable to send emails from the site and suspect it's because of excessive traffic again - log file below.

Has anyone any suggestions as to a fix or solution and how do I ascertain which module is causing the traffic?

Most of the emails are daily updates to research forums being sent to registered users

thanks

Ian

Hi

I have the subscription module loaded and have been having issues with sending notifications via my hosting company so I change to google smtp only to have the same issue. - as explained above

However after going into admin-config-system-subscriptions I found the following message:

12,457 active and 327 suspended items in the queue. So I purged the queue so tha it now reads

0 items active and o suspended items in teh queue

15 minutes later I checked and I now have 1307 active and 16 suspended items in the queue.

Google only allows 500 emails a day so clearly I am exceeding this.

It seems that something is generating emails on the site ? or is my logic totaly wrong?
If the former how do I trouble shoot?

thanks Ian

Core does not send emails on a regular basis as it has no subscription module by default. I suggest reviewing the settings of the subscription module and make a determination on how your users are using the site. It very well may be that you are beyond the resources any shared server or free SMTP will provide.
