It seems I signed up with Sun using sun.2.myuser a spamgourmet.com. That's how it shows the address when I look it up by the word "sun". It seems also that I signed up to something else from sun by using sun.10.myuser a spamgourmet.com.
The latter, sun.10, has started receiving marketing material. I'm pretty sure they would honor their opt out, but I think I need to send the opt-out e-mail from the sun.10.myuser a spamgourmet.com. I can't hit reply because it would go to the noreply e-mail, not the opt-out e-mail.
Ok, no problem. Go to the SG interface, look up my "sun" e-mail, but... I can _only_ send e-mail from sun.2.myuser a spamgourmet.com. I tried filling out the create new address, with word "sun", number "10" domain spamgourmet.com, but it said that word already exists and pre-selected sun.2.myuser a spamgourmet.com
... is there anything I can do about this?
BTW, the link at the top of the page (bbs.spamgourmet.com, very upper right corner) links back to www.spamgourmet.com, not bbs.spamgourmet.com..
