Hi I am having a problem, when I send an email from any of the accounts in cyber panel to another in the same server no problem.
If i send one from cyberpanel to a gmail account I dont receive it.
Help me please, anyone knows how to solve it?
Have you requested from your VPS provider open port 25? Does not matter even you opened from your end it’s blocked by provider end.
Most if not all of reputable VPS providers block mailing port to protect their IP reputation. You need to request them open port 25 and explain what kind mail you planning to send.
If you planning to send marketing/huge mailing list spam hosting your own mail server not good idea. Your IP get blacklisted very fast.
Hi Dreamer, I already requested to unblock port 25 but they said “Unfortunately we do not allow newsletters or marketing emails of any kind we recommend a third party party service” . Do you have any ideas or workarounds for us to send emails outside our web server?
Either get other VPS provider what won’t block port 25 but those are full of spammers and IP’s are all time blocked or use third party provider.
If you use harvested or bought email lists, running own mail server will get your IP blocked anyway very fast.
If they are not opening port then you have to change the provider
Check if 465 or 587 is open.
