You can fetch and send emails using your YunoHost instance from desktop email clients such as Mozilla Thunderbird or on your smartphone with applications like K-9 Mail.
Normally, configuring your mail client should be automatic, but if the autoconfiguration fails, you can do it manually following the instructions bellow.
### Generic settings
Here are the element you should enter to manually configure your mail client (`domain.tld` refers to what's after the @ in your email address, and `username` what's before @).
To manually configure a new account in Thunderbird, add the account information, then select port 993 with SSL/TLS for IMAP, and port 587 with STARTTLS for SMTP. Afterwards select 'Normal Password' for Authentication and click on 'Advanced Config'. You may need to accept the certificate exceptions for fetching mails and after you send your first mail. Don't forget to remove the dot before the domain name.
