I set up the email to board tool but it appears to be sporadically not working.
I've just sent something this morning to one of the boards, that worked fine last week, and had an error message saying:
Hello,
The Trello board email address you attempted to email,[email address I sent to], is invalid. You can get your email address for any board by going to "Email-to-board Settings" under the sidebar menu in that board.
For more information on sending cards to your board via email, please visit our help page.
Help section isn't helping me.
Any ideas why it's working one minute and then not the next?
