Hi there, We use Mods for Hesk on 2 installations (using the same hosting environment) The older version (one before the latest) works fine however the new installtion is having an issue

When trying to send a reply to the customer we get an error couldnt send email - when we turn on debug mode it gives us this error

Code: Select all

Error: 554 Transaction failed: Duplicate header 'MIME-Version'.

It seems that the MIME-Version is displayed twice.

We removed the installation and started fresh

First we installed Hesk - enabled smtp and sent an email. Works perfect

Then we installed mods for hesk and then redid our test and got the same error again

Any ideas how to get around the MIME Version being outputted twice?

Thanks

This will probably fix it?

I have tried that already and didn't make a difference

Thanks

When trying to send a reply to the customer we get an error couldnt send email

Are you referring to the email when sending a new reply, or are you clicking the "Resend Email Notification" button?

[deanwalker]

Thanks for the quick responses

This is refering to all emails

When i create a ticket i dont receive any emails, I only spotted this when replying to a ticket. I have not tried the resend email notification

here is a quick screen cast of the issue

Also just to point out,

This is a clean installation

Only settings changed was SMTP for Amazon SES

I tested on hesk before installing the mods and it worked fine

issue since installing the mods

Thank you for all your help

Heh, I see the issue.

In inc/email_functions.inc.php (you may want to make a backup of this file first in case things go awry), find:

Code: Select all

// Send the e-mail using SMTP
$headersArray = array(
    "From: $hesk_settings[from_header]",
    "To: $to",
    "Reply-To: $hesk_settings[from_header]",
    "Return-Path: $hesk_settings[webmaster_mail]",
    "Subject: " . $subject,
    "Date: " . date(DATE_RFC2822),
    "Message-ID: " . hesk_generateMessageID(),
    "MIME-Version: 1.0",
);
array_push($headersArray, "MIME-Version: 1.0");

Delete this line:

Code: Select all

array_push($headersArray, "MIME-Version: 1.0");

Save, upload, and test
