Connecting to mail on other clients (iphone)

[republicus]

@fearwoks,

according to panel/?module=services
"HTTP (port 80 is open)
FTP (port 21 is open)
SMTP (port 25 is open)
POP3 (port 110 is open)
IMAP (port 143 is open)
MySQL (port 3306 is open)
DNS (port 53 is open)
"

So I guess the ports are fine, also, I tried to connect with the ip directly and it didn't work, and I remember trying years ago before using cloudflare and it never worked, but for now I turned off their protection, the domain points directly to the server's ip.
Do you have any suggestions? I can offer an access to sentora if you wish, or create a test email and give you the password to see if it works with external clients

Whats your domain?
If your domain is m8hamedh.ml then you definitely need to give DNS some attention.

Try using telnet to connect to each port to see what's making it through your firewall.
Eg.:

Code:

telnet example.com 110

You can add telnet as an added Windows feature and use the above command in command prompt.
If you have puTTY, telnet is also integrated.

Any answer from telnet is a good sign. It may be a mail banner, login, etc.


Or, you could also run a Windows PowerShell command to check from Windows 10.

Code:

New-Object System.Net.Sockets.TcpClient("example.com" 110)

It should answer several lines:

Client                                : System.Net.Sockets.Socket
Available                            : 115
Connected                      : True
ExclusiveAddressUse         : False
ReceiveBufferSize              : 65536
SendBufferSize                  : 65536
ReceiveTimeout                : 0
SendTimeout                    : 0
LingerState                       : System.Net.Sockets.LingerOption
NoDelay                           : False
