How do I specify my e-mail address on NanoPool mining ZEC.

My config is:

@echo OFF

REM Change the following address to your Zcash taddr.

SET ADDRESS=MyTAddressHere

*I have also tried the following:

SET ADDRESS=MyTAddressHere:myemailaddressHere
*

SET USERNAME=%ADDRESS%.WorkerName

SET POOL=zec-eu1.nanopool.org:6633

SET SCHEME=stratum+ssl

bminer.exe -uri %SCHEME%://%USERNAME%@%POOL%

The problem is that I cannot change the minimum payment amount as the e-mail address (password) under Settings on Nanopool cannot be specified. I keep on getting "Incorrect Password" response from the settings page.

Am I missing something obvious?

Thank you
