<a name="68"></a><p class="title">Do not validate server certificates</p>
<p>If checked, Hesk will not validate certificates from the TLS/SSL server.</p>
<p>Certificate validation usually needs to be skipped if the server uses self-signed certificates.</p>
<p>We strongly recommend that you do <b>not</b> disable certificate validation on production servers and when connecting to third-party servers as it makes you vulnerable to man-in-the-middle attacks.</p>

<a name="70"></a><p class="title">Do not reply</p>

<a name="71"></a><p class="title">Returned</p>
<p>If checked, Hesk will try to detect and ignore returned emails.</p>
<p>For example, it will ignore emails sent from [email protected] and emails with a subject such as "Returned mail", "Undeliverable", "Out of Office" or similar.</p>

<p>This function will try to detect common email domain name misspelling and suggest a corrected version.</p>
<p>For example if customer enters user@<span style="color:red"><b>gmial.com</b></span> HESK will detect it and suggest
user@<span style="color:green"><b>gmail.com</b></span> instead.</p>
<p>HESK will compare email domains to the domains listed in <i>Email providers</i> list.</p>
<p> </p>
<a name="63"></a><p class="title">Email providers</p>
<p>A list of common email providers your customers use. HESK will use this list to try to detect mistyped email addresses.</p>
<p>Enter one domain per line, <u>without</u> the @ sign.</p>
<p>You can enter any number of common domain names, but try not to overdo it - enter just the most common ones.</p>

<a name="65"></a><p class="title">Notify customer when</p>
<p>Select when HESK should send an email notification to customers:</p>
<ul>
<li><b>when customer submits a new support ticket</b><br /><br />
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).<br /><br />You can use this to prevent
automatic replies to emails detected as possible SPAM by your server SPAM filter.<br />
</li>
<li><b>when a support ticket is marked as Resolved</b> (without replying)</li>
</ul>
<p> </p>
<p>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.</p>

<a name="61"></a><p class="title">Strip quoted reply</p>
<p>This function deletes quoted replies from all customer emails before they are converted into a ticket.</p>
<p>All emails sent to customers will start with this line:</p>
<p>------ Reply above this line ------</p>
<p>Any text below this line will be removed when and email is imported into ticket reply.</p>

<p>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.</p>
<p>Files over maximum allowed attachments limit will be ignored.</p>
<p>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.</p>

<p style="color:red">Notice: Unknown: Kerberos error: Credentials cache file '/tmp/krb123_0123' not found (try running kinit).</p>
<p>If this happens, try enabling the "Disable GSSAPI" option, then test the IMAP connection again.</p>

<p>The "Max recipients" count is a cumulative total of all the email addresses in the To, Cc, and BCc fields of an email.</p>

<p>Customer emails can be rejected by HESK when customer accounts are required, but the email address of the sender is not registered on the help desk.</p>
<p>Selecting this option will notify the customer that their email was rejected. To reduce spam, only one rejection email is sent every "Time between rejection emails" hours.</p>
<p><b>Note:</b> If an email is rejected due to spam or is considered a duplicate, no email will be sent to the customer regardless of this setting.</p>

<p>The amount of time to wait before sending a second rejection email to a customer, regardless of the number of emails sent.</p>
