Referring to fig. 1, a first embodiment of a method for sending a mail according to an embodiment of the present invention includes:
101. a first server receives a mail containing an attachment file sent by a user side;
the user terminal in the embodiment of the invention comprises an internet-based webmail or mail client terminal.
The first server may be a mail server for processing and sending mail to a destination domain server. Attachment files refer to documents, multimedia files or binary files embedded directly in the body code of the mail.
102. Judging whether the size of the mail is larger than the limit value of the destination domain of the mail to the size of the mail;
the mail server judges whether the size of the received mail is larger than the limit value of the destination domain of the mail to the mail size.
103. If the size of the mail is larger than the limit value of the destination domain of the mail to the size of the mail, sending the attachment file to a second server, and adding the storage address information of the attachment file on the second server to the mail;
if the mail server judges that the size of the received mail is larger than the limit value of the destination domain of the mail to the mail size, the mail is considered to exceed the size of the common mail which can be directly sent to the destination domain server and cannot be returned due to the overlarge attached file, and the mail is not suitable to be directly sent to the destination domain server. Mail contains attachment files that account for a large percentage of the size of the mail, and mail is generally rejected as being too large because the attachment files in the mail are too large. Thus, the mail server sends the attachment file to the second server, which saves the attachment file.
The second server in this embodiment may be a cloud server, and the specific storage manner may be that the attachment file is sent to the cloud server through a cloud hard disk or a file transfer station for storage. The cloud hard disk is a virtual hard disk which provides a user interface and permanently sends the attachment file to the cloud server, and the file transfer station is a storage device which provides the user interface and temporarily sends the file to the cloud server.
Further, the mail server adds the storage address information of the attachment file on the cloud server to the mail, and the storage address information can be added to the body of the mail or other positions of the mail, wherein the storage address information can be a link pointing to the storage address of the attachment file on the cloud server, and a user can obtain the attachment file through the link.
104. And sending the mail added with the storage address information.
