Hi this is a possible bug. In the past I would use the
'click here to send a message from this address'
link on the advanced page to send emails from one of my disposable addresses. I use pine in a terminal so I would not actually click on the mailto link that this generated, but instead I would just copy and paste the text of the address into pine. (I would not control click and select 'copy address' because then when I would paste this would munge the # into a %23)
Today I tried it and I got a bizarre mailto address generated. There were what appeared as two spaces dirrectly before the @ in the text of the email address generated. When I pasted it into pine the two spaces translated into %C2%A0. I am using Safari 1.2.3 (v125.9) as the browser, hope this helps in some way and thanks for the fantastic service of SpamGourmet.
