4.9.4. How to prevent messages going to spam

To increase the credibility of the messages you send and reduce the risk of them going to spam:

• To send mail, use SMTP instead of PHP mail function.
• Add the SPF record in the domain settings.
• Enable DKIM signature.

If mail is being sent from a VPS or dedicated server, you must specify a PTR record for the server's IP address. It should point to the domain, which in turn will be resolved to the same IP address.

If messages sent to your mailbox hosted by us are being spammed, you can try to take the following steps on your part:

• Check if the sender has been added to the blacklist. If it is there, remove it from there. Also add it to the white list.
• Check the filters for your mailbox in WebMail.Online and WebMail classic and make sure there are no filters that can move messages to spam. If there are, reconfigure, disable or remove them.
• Also, messages may be moved to spam by one of the mail clients or services connected to your mailbox. In this situation, you should check authorization log in your mailbox. If it is difficult to identify the problematic mail client, you can try change password of the mailbox. This will disconnect mail clients connected earlier from it. You can then observe the situation for a while using only WebMail.Online or WebMail classic. If the problem goes away, then that was the cause. After that, if necessary, you can try to identify the problematic client by alternately specifying a new password in the used mail clients and monitoring the situation. If services like myMail were used, you may need to disable the mailbox manually directly in these services.
• Lower the antispam level in your mailbox settings.
