问题
I am trying to retrieve emails with ruby mail gem, in the examples it says that Mail.last will retrieve the last unread email https://github.com/mikel/mail#getting-emails-from-a-pop-server but it returns just the last email no matter whether it has been read before or not.
Does anybody know how to get only unread emails?
回答1:
This question was answered in Need help on reading emails with "mail" gem in ruby
However the answer was not accepted - don´t know why. Also the question did not mention "unread email" nor the [mail-gem] tag so it was not obvious to search.
The answer points to the solution on the ruby-gem issues report https://github.com/mikel/mail/issues/258
