[electrum] sendtx transaction rejected by memorypool

[hathmill]

Hi,

when I do this:
/usr/local/bin/electrum -w wallet mktx -s 1CenozscLTCVeRM4EkGFChLWiu8wGMiV92 -c 1KieWL67FuQ7GCRWfopMEMXuF9WKZbbEpv -f 0 1AshiaAo4cVhpPoFEBQARu4GTfdCy7SJuM 0.00001 > txfile

and then this:
/usr/local/bin/electrum -w wallet sendtx `cat txfile`

I get this:
Connected to electrum.novit.ro:50001
error: error: transaction rejected by memorypool: Transaction not accepted to memory pool.
0100000001a30162<...>

Why did I get that error. I picked the change address from the wallet where I find it listed as a change address (not sure what a change address is really). Could it be that my fee is set to low?

I did read the electrum wiki, but besides something about double spending I did not get any help. The thing is that even though I have not sent the tx before I get this error. One server responds no such method, but most "rejected by memorypool". Can anyone help me? I will send the coins to your adress if you just tell me how to do it!

Ah to protect against ddos attacks, small transactions must pay. So, probably I must pay higher fee.
