Question

How to change the maximum attachment size for webmail on the Windows Plesk server?

Answer

Horde Webmail

  1. Connect to the server via RDP.
  2. Edit the%plesk_dir%webmailhordeconfphp.ini  file and change the PHP settings for Horde.
    For example:

    C:> type %plesk_dir%webmailhordeconfphp.ini | findstr max
    ...
    upload_max_filesize = 64M
    post_max_size = 128M
    ...

  3. Modify also horde attach_size_limit value at %plesk_dir%Webmailhordehordeimpconfigconf.php, it should be set to 0 (unlimited):

    C:> type %plesk_dir%Webmailhordehordeimpconfigconf.php | findstr attach_size_limit
    $conf['compose']['attach_size_limit'] = 0;

    Note: Set higher values if it is required.

MailEnable Webmail

  1. Connect to the server via RDP.
  2. Go to Windows Mailenable > Servers > localhost >Services and Connectors > right-click on SMTP > properties > Outbound tab
  3. Under Limit outbound size, specify a higher value in Maximum field;
  4. Click OK;
  5. Stop and start the SMTP service to apply the new change at Windows Mailenable > Servers > localhost > Services and Connectors > right-click on SMTP .

    Note: If the issue persists, apply the solution described in MailEnable KB

    Note: Set higher values if it is required.
