When you add an attachment to your email that is larger than 20MB, Mail asks if youвЂ™d like to use Mail Drop to send it. If your email was rejected by the server because the file was too large, you might be able to get around the size limit using Mail Drop.ДЄll you need to do is send an email using the Mail app.

Get a bigger limit with iCloud Mail DropДЄppleвЂ™s Mail Drop feature makes it possible to send email attachments up to 5GB in size. However, even if your email provider allows larger attachments, your Internet service provider might still enforce a smaller size limit. You can enable a larger email attachment limit using Mail Drop with iCloud (explained below), which lets you send up to 5GB of attachments with each message. But itвЂ™s not enough for uncompressed photos or videos. Typically, email providers limit attachments to 20MB, which is plenty of space for most documents. It looks like this: You might see an alert saying your file was too large.ДЄttachment size limits stop you from sending large email messages to people. The message was rejected by the server because it is too large.

However, other many commands are unkown, like sysctl, etc, and espcially those used to manage a server.

I know basic commands like ls, pwd, rsync, ssh, etc. So I have to update the info (IP and domain matching) in my name server (the name server is provided by ).ДЄt last, macOS is derived from Unix / BSD, so I would like to learn the command line administration of my macOS, via terminal. If I want to access my server from WAN via domain, I need to match the public IP and the domain. The reason for this is that my public IP address changes over time (several hours to a week, maybe). All private network will down if this happens.Д¦.The server has to update the dynamic IP with my registered domain periodically. For instance, if I am not at home (server / router is at home), and away from my home thousands of miles, once I reboot the server / router, the connection breaks and I am about to lose the access to the server / router. Occasionally, I need to reboot or turn off my server / router, and if I had to dial PPPoE manually, things got complicated. So anther must-enabled feature of the server is that, the server is able to dial PPPoE automatically. For hosts connected to subnet 2, I plan to use static IP and these hosts are wire-connected hosts like iMac, Win, Linux, printer, etc.ДҐ.My ISP assigns me public IP address via PPPoE. So to assign IP address by DHCP is recommended. I about to connect two APs to subnet 1, and these APs are for wireless devices, like smart phones, iPads, Androids, MacBook Pro, etc. Д¤.DHCP function on server is recommended to be turned on. WAN > (ethernet 1) Server / Router (ethernet 2) > switch (to connect some hosts) > router 2 (to split the private network into 2 subnets) > other hosts.

So the third function must be enable on the router / server is port forwarding. To fix this issue, I think I need the port forwarding function. Same issue exists for SSH server (port 22). For instance, the web service 80 port would be changed to a random port number between 105. This is due to the fact that PAT would change the port. Although the PAT allows hosts in private network to exchange data with the wide are network, as SSH server, web server, PAT is not able to make them be accessed from the wide area network. So these hosts in the private network would behave like a SSH server, and so on. Consequently, the PAT function must be enabled on the server.ДЈ.I need to access anyone of my host in the private network (behind the server) via SSH, Apple Remote Desktop, etc. So to let them be able to access the Internet, PAT is the first-of-choice (because I have only dynamic public IP address). Beside this server, I have other hosts and I assigned private IP addresses to them.

Interestingly, the ethernet connected to the public network would be a host of the wide area network, and the ethernet connected to my private network would be the gateway of my private network.Дў.The sever must provide PAT function. To move a packet from ethernet 1 to 2, or vice verse vice. As a server it should have funcitons like DHCP, NAT, NAPT, Web service, SSH service, etc.ДЎ.The server must support packet forwarding function, which is the basic function of a router. I want to set my macOS as a server and a router.
