Arrghh!!! , It happened again. I deleted one of my student's email that was sent to me regarding the paper work that i gave at the first class. GMail marked the message as SPAM and i didn't saw it when i clicked the link that will delete all SPAM messages forever. I saw it in a flick and then it disappeared forever. I guess i should be more careful again when deleting SPAM messages forever. Usually, GMail always give the correct marking, but lately, some emails can bypass GMail spam protection and reach my inbox.
Most of the emails that went to SPAM directory came from Yahoo domain. Is it a form of rival? I don't know, but they should not do that just to win business.
I have given an announcements and i will tell the students to re-send the email to me and gave CC to other email address, just to be sure that it won't be deleted in both email.
