Emails
The way the email manager works
Originally, emails were sent from the server immediately, right after they were sent from the ISPadmin system. However, when, for example, 2000 invoices were dispatched at the same time, the system could become overloaded and the destination servers began gradually to reject these emails because of the sheer number of emails received in such a short time. Legitimate emails were marked by some servers as spam because they were sent in quick succession. Some emails returned undelivered.
Now all emails to be sent off are placed in the queue of the email manager and are sent in successive steps (X emails per 5 minutes) so that SMTP server email sending limits are not exceeded.
Furthermore, the sending of emails is optimized according to the destination domain.
Example:
You want to send a total of 500 emails. 100 of those are to be sent to the seznam.cz server. 400 of those are to be sent to other email servers. The number of emails sent to one domain never exceeds the set number of X emails per 5 minutes (default: 10 emails per 5 minutes).
The sending proceeds as follows:
- The 400 emails mentioned above (different email servers, different domains) will be sent immediately.
- The 100 emails mentioned above (seznam.cz) will be split into 10 groups of 10 emails. The first group of 10 emails will be sent immediately. The rest will be sent in several successive steps (10 emails per 5 minutes).
Email queue configuration
You can specify the maximum number of emails that will be sent to one domain within 5 minutes in the mail_manager_domain_queue key in Settings Syst. settings General. The default value is 10. That means that a maximum of 10 emails will be sent to one domain within 5 minutes.
Each email has a certain preset priority (High, Normal, Low). By default, the priority is set to Normal. You can set it differently for different emails when sending emails from the Client card.
Queue
This page displays the email queue.
In the overview, you can find the email addresses to which individual emails are to be sent, the subjects and texts of these emails and the times when they are to be sent. You can remove individual emails from the queue by clicking on the 
icon.
If there is not a single item in the table, it means that there is not a single email in the queue (all of them have already been sent). If there are some items in the table, you can batch delete them by clicking on Delete unsent emails from queue.
If you are trying to send a large number of emails to one and the same email server, you have to keep in mind that they will be sent in batches (5-minute intervals) so as not to be marked as spam.
History
This page provides an overview of all emails sent from the ISPadmin system. You can choose the type of emails you want the system to display (e.g. automatic reminders, invoice emails, emails from the Client card) in the menu on the left-hand side of the page.
The overview itself provides the following details: when a given email was sent, to whom it was sent, to what email address it was sent, what the subject and text of it was, whether it was sent successfully, whether it contained an attachment, which priority it had, and who sent it.
With the help of the Priority filter, you can arrange for the system to show only those emails that have a certain priority. You may also perform a fulltext search on the list. Entries can be sorted by a particular column by clicking on its header. You can return to the default state by clicking on Default.
| Select a particular type of change. There might be different types of changes for different types of emails (depending on the characteristics of a given type of emails). You can choose a specific type of change on the level of the whole group or on the level of its subgroups. |
