Mail.baby is an email smarthost that helps prevent spam, phishing, viruses and email compromises. As such each email is scanned to determine if the email will deliver. In addition a few steps must be done to ensure email can be sent.
1) Sign up for a mailbaby account and get an active mailbaby username
2) Ensure all domains follow MailBaby’s SPF format. Email may not deliver if this step is not taken.
3) If you are using the API, in addition to SPF you must also add on a dns record to authorize the domain for sending VIA the api.
4) If you are using a server or VPS, port 25 may be blocked. This is very common. Mailbaby offers a few ports that can be used
The following require startTLS
– 25
-587
-2500
Alternatively port 465 is available with a pure SSL connection.
5) It is important a authenticated header is used. The set up for cPanel, Directadmin, or Postfix all include the Authenticated Header.
6) All mailbaby orders start with a stricter filter while email is learned as spam / ham called a New User Filter. This is not simply based on account age, and is based off SMTP responses and email reputation. Please contact support with questions on this.
7) When reporting a false positive, ensure SPF is set up. A false positive will also contain a bounce back message with some debugging information. There is a not spam button that will open a request on that specific bounce back. A response may be given on this to the mailbaby owner, not the email address owner, should more clarification be needed. A false positive will not deliver the message and make take a few hours to process. Once an email is bounced, the content is no longer available. Should more information be needed support staff may ask for the message to be resent to a false positive email. Mailbaby staff does not have the ability to check into the content of a message once delivered or bounced.
