Once you have set up at least one email queue in Kayako Classic, it is worth taking a look at some of your system-wide settings, to make sure your queues are operating at optimum efficiency.
In this article, we will go through and look at some of the settings that you should be aware of to keep things running smoothly.
Optimizing your email settings
Within the admin control panel, you will find a handful of system-wide settings under Email Parser and then Settings on the sidebar.
On the page that opens up, you will see a long list of email configuration options. We would not go over all of them in this article since they apply to a variety of different email-related processes. Instead, we will focus on the settings that are most critical for safeguarding the performance of your email queues.
- Maximum number of emails to download in a batch
Right up top, under the POP3/IMAP Email Download Settings heading, this setting controls the maximum number of emails fetched into Kayako Classic any time it checks an email queue. By default its set to '20', which is fine if your helpdesk has a small number of queues and doesn't routinely fetch large email attachments.
If, however, you find yourself with a large number of queues and regular email attachments exceeding 8 MB, we recommend changing this setting to '10' or lower.
NOTE: If you do not adjust this setting to accommodate a large number of queues or large attachments, it can significantly impact the performance of your helpdesk.
- Email size limit
Next, on the list, this setting lets you restrict the size of each email coming into Kayako Classic. Any incoming email that exceeds this size limit will not be fetched from your email server. These limits include the email's content and attachments.
The default is 2048 KB, and the only max is that it cannot exceed the
php_memory_limit value set in your
php.ini file. That being said, we do not recommend setting a high limit here. The larger the attachments you receive, the higher the risk that your helpdesk's performance will suffer.
Prioritize email content type
You will find this setting in the middle of the Email Parser Settings section:
Here, you can control whether Kayako Classic captures any HTML formatting from incoming emails. You will note that the page says 'Plain text highly recommended' and while that used to be the case, capturing HTML formatting has become the standard for most of our users.
So, to allow Kayako Classic to capture HTML content from incoming emails set this to 'HTML.'
You will also need to visit Tickets and then Settings on the admin sidebar and make a couple of changes there. In the middle of the page, you are looking for these:
With Prioritize email content type plus the two HTML handling options set, Kayako Classic will be able to capture any HTML formatting from incoming emails and render it in your support tickets.
- Maximum email log size
The last setting back on the Settings: Email Parser page, this one lets you establish a maximum size (in kilobytes) for the email logs that Kayako Classic retains. Any parser log that exceeds this limit will be discarded.
By default, this limit is set to '50,' but we recommend you increase it up to 5000 KB so that your logs for larger emails are also stored. Having these logs can be critical when trying to diagnose email parser issues.
