The U-mail system is easy to play with mailbox capacity and large attachments

I believe you often have this experience: When I receive an email, it takes a long time to read it, and a large attachment is sent. The attachment contains a picture or video, which not only slows down the download speed, in addition, for the "mobile phone party", a waste of traffic is really hateful, but in the multimedia era, the sender is afraid that you cannot understand his intention, and the entire large file is required. In daily work, the nature of your work may have nothing to do with pictures, such as media editing and text writing. Therefore, images and videos are not welcome to affect the network speed, while images are useful to others, so the question is, can you simplify the image, for example, a small link, so that the people who need it can download and watch it, and those who don't need it can simply ignore it? Don't worry, xiaobian tells you that the U-mail server software can do it.

Let's summarize the requirements. For the mailbox capacity, if you are the mail system administrator of the company, you want:

1. Allocate enterprise mailbox capacity to some departments or employees, because some employees have fewer mailbox opportunities;

2. Restrict the mailbox capacity of certain departments or employees. When the mailbox capacity is greater than this capacity, take appropriate measures;

3. In response to requests from employees in special positions to restrict the receipt of mails containing certain types of attachments, this requirement is closely related to the first one. Because the mailbox size is small, it is naturally necessary to receive attachments;

4. In other positions, such as business personnel, they need to send emails frequently. In order to avoid the troubles caused by large attachments to recipients, they need to be simplified as links.

I often say that the features of the U-mail system are very rich. You can see that there are so many requirements for a small enterprise mailbox capacity problem, the solution is also quite simple:

1. First, after you follow the recommended domains of your department or branch, you can log on to the umail email server's hyper-Domain Management backend and set the domain size, for example:

You can switch between different domains, fill in numbers in the "domain capacity limit", and assign quantitative values; in "User mail default capacity", enter a number to limit the default mailbox capacity when adding users.

Ii. Concerning the restriction on the mailbox size, in fact, one of the methods described above is to limit the average mailbox size under a domain name, you can also find an email address in the "email list" and modify its capacity. In addition, to restrict the account, select "Settings"> "Reference" on the left side of "system management background interface" of the U-mail system, for example:

"An account that exceeds the quota can accept emails but cannot send emails" means that an account can receive emails but cannot send emails when it exceeds its quota. Of course, we can also remind users in advance to delete emails in time. For example, when the capacity reaches 85% of the quota, enter the number "85" in the box ".

3. restrict the types of attachments to be received. Also, on the left side of the "System Management Background interface" of the U-mail system, choose "security"> "content filter"> "management/attachment ", for example:

In the "restricted attachments" box, restrict certain types of attachments as required, and click "add" to add them to the list one by one, you can also select to only receive emails containing certain types of attachments.

4. If we need to increase the mail transmission speed, we can use the "Network hard drive" to simplify large attachments into small links, as shown in:

You can select "Upload File". The uploaded files can be shared. After sharing, there is a URL address, which can be downloaded after being sent to someone else.

Through the introduction of the series above, you must have understood how to control the capacity? Of course, xiaobian does not require you to compress the mailbox size for "bitter days". After all, in this "Big Data Era", matching a large-capacity mailbox is necessary, in fact, you don't have to worry about the insufficient capacity of the U-mail system. Theoretically, the capacity of the U-mail system is infinite, but in fact it only depends on the capacity of your server's hard disk.
