Invalid "To" e-mail address error

    Hi, I’m using Jetpack’s Contact Form plugin along with Postman SMTP to send emails.

    Most of the emails I have sent via the contact form have worked fine, apart from three: the only difference with these three is that two of them are from a hotmail account, and one is from a ymail account. (One of the ones that did work was from a @yahoo.co.uk account.) When I say “from”, what I mean is the email address that is inputed in the “Your Email Address” box in the contact form.

    When I initially checked the Postman SMTP Email Log, all of the emails were shown to be Sent. However, when I clicked “Resend”, I got the following error message:

    Invalid “To” e-mail address “a:1:{i:0;s:31:”[email protected]”;}”

    I get this error message even when clicking “Resend” on the ones that initially DID work.

    Connectivity test returns no errors, although it does show the warning: “Warning: connected to yahoo.com instead of co.uk.”

    My Postman SMTP settings are:
    -ACCOUNT-
    Type: SMTP
    Outgoing mail server hostname: smtp.mail.yahoo.co.uk
    Outgoing mail server port: 587
    Envelope-From Email Address: [email protected]
    Security: STARTTLS
    Authentication: Login
    -MESSAGE-
    Email Address: [email protected]
    [x] Prevent plugins and themes from changing this
    Name: AMA Surveyors SMTP
    [x] Prevent plugins and themes from changing this
    [x] Disable e-mail validation

    Hope this is enough information. Thanks in advance.
