Single quotes causing email verification fail from AmazonSES

  • Hi,

    We are using the WP Discuz plugin alongside your SMTP plugin.
    We are running into an issue with the comment notifications emails being sent to authors.
    The emails are failing with a returned 554 Message rejected: Email address is not verified
    We are using Amazon SES.

    I seem to have narrowed the issue down to single quote characters making their way into the From: header, for example (from the Session Transcript — i’ve edited the domain and gmail address):

    From: ‘Grant’
    Sender: [email protected]
    To: [email protected]

    which fails

    but when I am using the “Prevent plugins and themes from changing this” on the name field (with “Grant”), it works, and I see this in the transcript.

    From: Grant
    Sender: [email protected]
    To: [email protected]

    Any advice here would be appreciated.
    Cheers.

  • Hi,

    Can you tell what “sent” that email?

    WordPress Core messages (password reset etc..) or specific plugin (like a contact form).

    Hi,

    It is the email sent to an author notifying them that a comment has been posted on one of their articles. When the commenter is a logged in user, it fails, but when they are not a registered user it works fine.

    Originally I thought it was the wpDiscuz plugin that could be causing the issue, but I have now disabled it and I’m getting the same issue with the standard comment system.

    – here is an example, this is the error in the log

    Message rejected: Email address is not verified. The following identities failed the check in region US-EAST-1: ‘Eric Martin’

    – and here is the corresponding full transcript (with private info removed)
