Check to see if your hostname or IP addresses are listed on major anti-spam databases (blacklists). Being blacklisted can result in email delivery issues.

Our free DNSBL test tool is great for running one-off checks when you think you might have a problem sending email. Administrators often do not know if their domain has been added to any of the major email blacklists. If you are an email Admin and concerned about the possibility of being blacklisted, try the Dotcom-Monitor ongoing blacklist monitoring service - free for 30-days. Dotcom-Monitor's DNSBL service sends a proactive email, SMS text message or phone call notifications as soon as your domain or IP addresses is detected on a blacklist.
