Hello, i want to ask about change port mail server 25. I'm using digitalocean and port 25 on the block, I have to use port 587 or 465. how do I change port 25?

I have the same problem @aaPanel_Jose , @aaPanel_Jose ?

RavenRAMIREZ perdiawan Port 25 is necessary for communication between mail servers, can not be change

perdiawan contact digitalocean and tell them to open port 25 for you. I use contabo they have all open ports. I have never had a problem with them.

I also need to change, I use digital ocean, I even opened a ticket, but they said it would only work on port 587

angelitoflow Were you able to solve the problem? because digital ocean does not accept port 25 even

If port 25 is necessary then it means that the mail module on your panel is bugged because it was working perfectly a week ago and suddenly it crashes @aaPanel_Jose , @aaPanel_thisyear

RavenRAMIREZ Please check whether the service status of the mail server is good and provide the mail server log

Change Port Mail Server 25

aapanel_power

rafaelfmachado Hello, port 25 is the protocol of 7 post offices, unless we are strong enough to shake the international postal organization to give me the freedom to use other ports, or to ask the server operator to open port 25. Otherwise we will have to accept this reality.

aaP_biswajit_technopoint

rafaelfmachado if i open 587

rafaelfmachado where i need to open 587 465 port?

rifkialibabacloud

aaPanel_Kern

Hello, it is recommended that you use a relay or a third-party mail server provider
