Right click the existing mail account then select Property to open the dialog box, select  Send, the following items will be shown in the box.

Message Format: You may send mails by  MIME or UUEncode format. We suggest you choose MIME format due to MIME is recommended by SMTP Protocol and compatible with many software.

Auto encoding text: When tick this check box, Foxmail will auto encrypt Chinese words and other none ASCII characters into 7 bit by Quoted-Printable. Although the existing Internet is compatible with 8 bit transaction, however, according to the many documents, some mail server or gateway will limit the 8 bit transaction, therefore the encryption is strongly recommended.

Remark: Attachment will be encrypted into 7 bit by base 64 protocol.


Allow 8 bit chars in mail header: Do not encrypt mail header information if the check box is checked.

Check new mails after sending: When select this check box, the original function of Send bottom will switch to Send and Receive.

Move the sent mails to folder "Sent": If the mail still be save in Outbox after sent out, it is probably because you didn't select this check box.

Default E-mail domain: Type the domain name of the E-mail then you can only type the recipient's account name when composing mails. For example, set up foxmail.com.cn or @foxmail.com.cn as the Default Domain Name, then you can only type abc when sending mail to abc@foxmail.com.cn
