I just signed up for R-help 2 days ago, and received an *Invalid confirmation string:*2beb5b0883f29fae71a80fcb30324117ec9ece94 when confirming subscription. I am receiving e-mails in my inbox with about 40% of individual e-mails saying across the top "this message may not have been sent by: name@somee-mail.com." Is this cause for concern? Should these messages be reported as phishing, and should I mark messages received in my inbox with the message "this message may not have been sent by. . ." as spam? -- Matilda Gogos matildaelizabethv@gmail.com [[alternative HTML version deleted]]
