I'm currently receiving Plusmail in iPad Mail for one of my mailboxes but I am unable to send any. I get the error message, Cannot Send Mail: The username or password for "smtp.plus.net" is incorrect. And yet the username (including + with the mailbox name) and password are correct and are working on other devices and with Webmail. This is new. I've been using iPad Mail with Plusmail over a decade. Is anyone having similar problems or able to suggest a fix? Thanks.
