Postfix 出站邮件未通过 Gmail 的 SPF 检查

设想

我已经用 mediatemple 接收邮件很多年了，但现在 godaddy 收购了他们，他们已经切断了我的出站邮件，当我打电话过来时，他们正在推送 microsoft 360，所以我决定滚动自己的邮件。

我用 spf 设置了 postfix，除了 gmail 每次都会关闭我的测试电子邮件外，一切似乎都很好：

<[email protected]>: host gmail-smtp-in.l.google.com[74.125.137.27]
    said: 550-5.7.26 This mail is unauthenticated, which poses a security risk
    to the 550-5.7.26 sender and Gmail users, and has been blocked. The sender
    must 550-5.7.26 authenticate with at least one of SPF or DKIM. For this
    message, 550-5.7.26 DKIM checks did not pass and SPF check for
    [ve.x.vesrv.com] 550-5.7.26 did not pass with ip: [x.x.x.x]. The
    sender should visit 550-5.7.26
    https://support.google.com/mail/answer/81126#authentication for 550 5.7.26
    instructions on setting up authentication.

问题

邮件被发送到我自己的域，但如何才能将其发送到我的 gmail 地址？
