POP3 Fetching stops working when using german umlaut äöüß in "mail from"

POP3 Fetching works fine until a user with umlaut in "mail from" sends a ticket.

Here in this example
User Jürgen P**** send to IT.Ticket@******.de

The mail header looks like this

Received: from mail.******.local ([::1]) by
mail.******.local ([::1]) with mapi id 14.03.0319.002; Mon, 10
From: =?iso-8859-1?Q?P****=2C_J=FCrgen?= <Juergen.P****@******.de>
To: IT Ticket <IT.Ticket@******.de>
Subject: Testmail....
Thread-Topic: Testmail....

The debug of
******/inc/mail/hesk_pop3.php
shows:

#!/usr/bin/php -q
Connected to the POP3 server "mail.******.local".
User "IT.Ticket" logged in.
There are 2 messages in the mail box with a total of 10301 bytes.
Parsing message 1 of 2.


While parsing the mail ist stops working.
Is it possible to change the parsing options to except german umlaute?

Thanks a lot

Testmail was send
Sender: Jürgen.P****@******.de

It imported just fine in my test setup?



If you login into webmail, do you actually have 2 messages in the mailbox or only one?

Hello Klemen

I think it's a problem in combination with our Exchange Server
Internaly we got a "=?iso-8859-1?Q?P****=2C_J=FCrgen?= <Juergen.P****@******.de" as Sender

The testmail you got was send via our sendmail proxy after virus scanning the mail.
The sender field is reduced to "<Juergen.P****@******.de"
So there is no problem for your import.

Can you tell where the mail parsing happens ?
So I can change it on my own.

Thanks

The "From" in the email you sent was actually set to this:

Code: Select all

From: =?iso-8859-1?Q?Pauer=2C_J=FCrgen?= <Juergen.Pauer@DELETED.de>

You can also see from the screenshot in my previous post that sender name was parsed correctly.

Files responsible for the parsing are:
- inc/mail/email_parser.php
- inc/mail/mime_parser.php
- inc/pipe_functions.inc.php
