A that comes with an e-mail is an attachment.
Emails are not files, so they do not have extensions.
There are two types of Yahoo accounts (Basic and Plus) and each has different options available to backup your emails.Yahoo PlusThe Yahoo Plus account is $19.99 and has full POP3 ability, allowing the customer to use an offline mail client like Microsoft Outlook, through which you can create a pst file to backup the email. Mozilla's Thunderbird is another offline mail client that offers backup solutions.Yahoo BasicThe Yahoo Basic account is the standard account most users have. While certain offline mail clients are available, they usually only grant access to the inbox due to the POP3 limitations on the account. This means that any mail not in the inbox can not be viewed through the offline mail client.BackupWith or without an offline mail client there is also the option to convert your email to a PDF file. This can be done one email at a time by downloading a PDF printer. There are free and paid versions available.You can also convert several emails to a single PDF online as some sites are able to navigate around the POP3 limitations of the Yahoo Basic account.
