Webmail not sending emails

[Michaelloyds]

I am having this issue with my mail server.

I f I use webmail, my mails get delivered to any external e-mails but on mail clients, my e-mails are sent but are not delivered.

I will appreciate any solution to this please

Hey there! It's possible that your hosting provider is blocking the ports used to connect to your machine, or your local ISP is blocking them. For example, I can not use port 25 from my home, and need to user an alternate port to connect using a client.

Can you let me know the error you receive when you try to send a message from the client, or are you saying you don't receive an error but they are just never received by the server?
