Horde webmail displays the alike warnings instead of the messages titles in the interface:

The message: "<message subject>" (123123123 Bytes) exceeds the fetch size limit


  1. Find out what PHP configuration file Horde uses by accessing the following URL:

    '' should be substituted with your actual domain name.

  2. Correct Horde configuration files and increase the following limit (by default it is 4MB):

    [root@ppa2 ~]# cat /etc/psa-webmail/horde/imp/conf.php|grep fetchmail|grep size
    $conf['fetchmail']['size_limit'] = 4000000;
  3. Increase the following PHP settings in the configuration file that was determined on step 1:

    # grep -E "upload_max_filesize|post_max_size" /etc/php.ini
    upload_max_filesize = 64M
    post_max_size = 128M
