can't send e-mail with attachments: Winsock Error 10054 Connection was reset by the other side!

When I try to send a e-mail with attachments I get a winsock error: Winsock Error 10054 Connection was reset by the other side! on the other mailserver (MDeamon). Normal messages can be send.

You're trying to send a massive amount of information through the socket, so the output buffer of the system becomes full.
You're trying to send data through the socket to the remotehost, but the remotehost input buffer is full (because its receiving data slower than you're sending it).

Known causes are:
Loss of connection to the remote socket
A connection can reset due to a timeout or a reboot of the remote system.
A duplicate IP address on your network
A misconfigured firewall or proxy server
A firewall or proxy server may block the connection.
Lost of packets or an aborted transfer
If the remote server stops responding, or if too many packets are dropped, or if the remote system aborts a transfer, it can cause a 10054 error.

Or simply the webserver on the other side is rejecting the mail
