Auto-discover settings

Email clients such as Outlook, Thunderbird and (very probably) Apple Mail for MacOS can use 'auto discover' techniques to get the server information automatically - this makes configuring email programs much easier. To enable this, your domain needs two extra DNS entries:

autoconfig    CNAME  autoconfig.mail.aa.net.uk.
autodiscover  CNAME  autoconfig.mail.aa.net.uk.

If they are not there already then you can add them, or ask Support staff for help. Once added, the imap/pop3/smtp settings should be retrieved during the setup process of adding a new email account to your email program.

Not all (or not many) email clients support this method of finding the server details, but it will make configuring Thunderbird or Outlook much easier.

You may also wish to set up SRV records (RFC 6186), as some email clients will use these to locate email services, eg:

_submission._tcp     SRV 0 1 587 smtp.aa.net.uk.
_imaps._tcp          SRV 0 1 993 mail.aa.net.uk.
