Setup Mozilla Thunderbird Autoconfig
We're all lazy sometimes.
If your email users commonly use Mozilla Thunderbird as their preferred email client, you can help them out get started by setting up autoconfig for your domain. Thunderbird autoconfig automatically detects mailbox configuration for a given email address when adding a new account to Mozilla Thunderbird. With it, your domain's email users do not have to enter the manual configuration of IMAP and SMTP server.
Adding Thunderbird autoconfig support to your domain is simple. Add a CNAME record of autoconfig.yourdomain pointed to autoconfig.migadu.com and you are done.
