Do not validate server certificates

If checked, Hesk will not validate certificates from the TLS/SSL server.

Certificate validation usually needs to be skipped if the server uses self-signed certificates.

We strongly recommend that you do not disable certificate validation on production servers and when connecting to third-party servers as it makes you vulnerable to man-in-the-middle attacks.

Close window

Do not reply

If checked, Hesk will try to detect emails sent from "Do not reply" email addresses and ignore them.

Examples:
do-not-reply@example.com
do_not_reply@example.com
no_reply@example.com

Close window

Returned

If checked, Hesk will try to detect and ignore returned emails.

For example, it will ignore emails sent from mail-deamon@example.com and emails with a subject such as "Returned mail", "Undeliverable", "Out of Office" or similar.

Close window

Duplicates

If checked, Hesk will detect and ignore an email if Hesk has already processed an email with the same message within "Timeframe" seconds.

When testing email to ticket functionality, either disable this setting or send test emails with unique messages.

Close window

Email Loops

Settings to help detect email loops created from autoresponders or undeliverable email.

Any number of emails higher than Max Hits from an email address within Timeframe seconds will be ignored by email piping.

Set Max Hits to 0 to disable loop detection.

Close window

Detect email typos

This function will try to detect common email domain name misspelling and suggest a corrected version.

For example if customer enters user@gmial.com HESK will detect it and suggest user@gmail.com instead.

HESK will compare email domains to the domains listed in Email providers list.

Email providers

A list of common email providers your customers use. HESK will use this list to try to detect mistyped email addresses.

Enter one domain per line, without the @ sign.

You can enter any number of common domain names, but try not to overdo it - enter just the most common ones.

Close window

Notify customer when

Select when HESK should send an email notification to customers:

- when customer submits a new support ticket
  Note: if ticket is submitted over email (email piping or POP3 fetching), HESK can skip sending new ticket notification to the customer if the email subject contains one of the tags listed in the text box (one tag per line).
  You can use this to prevent automatic replies to emails detected as possible SPAM by your server SPAM filter.
- when a support ticket is marked as Resolved (without replying)

Note that notification preferences are set individually per ticket when staff replies to a ticket or when staff submits a ticket from the admin interface.

Close window

Strip quoted reply

This function deletes quoted replies from all customer emails before they are converted into a ticket.

All emails sent to customers will start with this line:

------ Reply above this line ------

Any text below this line will be removed when and email is imported into ticket reply.

Close window

Require message

If enabled, emails from email piping or POP3 fetching will be ignored if they contain no message.

If disabled, even emails with no message will be turned into tickets.

Close window

Embedded files

Enable if you wish HESK to save embedded email files (for example embedded images) as attachments when importing tickets over Email piping or POP3 Fetching.

Files over maximum allowed attachments limit will be ignored.

Note that with HESK file attachments have priority over embedded files. For example if you allow 2 file attachments and receive an email with 1 file attachment and 3 embedded images, HESK will save the file attachment and first embedded image, the rest will be ignored.

Close window

Multiple emails

If a customer tries to enter several emails (separated by comma) into the Email field when submitting a ticket HESK will only use the first email by default and ignore any other emails.

To allow customers to enter multiple emails enable this feature by checking the box.

Close window

Confirm email

If selected, the "Submit a ticket" form will show a "Confirm email" field forcing the customer to type the email address twice. This helps avoid typos in email addresses.

Close window

Open only

If checked then the "Forgot ticket ID" email (email sent to remind customers of their ticket tracking ID number) will only list open tickets and ignore resolved ones.

Close window

Email formatting

Determines which email formats are included when sending out emails. Options include:

HTML with plain text alternative from plain text template (default) - emails will be sent as HTML. Hesk plain text email template content will be used for the alternative text in the email (multipart/alternative).
HTML with plain text alternative generated from HTML template - emails will be sent as HTML. The alternative text in the email (multipart/alternative) will be generated by converting the HTML template to plain text. Hesk plain text email templates will be ignored.
HTML only - emails will be sent as HTML only without multipart/alternative.
Plain text only - emails will be sent as plain text.
