Mailheader problem after upgrade to 2.2.0
Hi,
A user on my system gets the below problem when sending a mail with an attachment. I (successfully) upgraded the webmail again today because another recent post suggested this solution. Still the user gets this error:
Warning: Header may not contain more than a single header, new line detected. in /home/admispconfig/ispconfig/web/webmail/inc/class.uebimiau.php on line 467
Warning: Cannot modify header information - headers already sent by (output started at /home/admispconfig/ispconfig/web/webmail/inc/class.uebimiau.php:467) in /home/admispconfig/ispconfig/web/webmail/inc/class.uebimiau.php on line 469
I hope you can help me..
