Ok let me try again. I have setup a mail server which I have hosted in google cloud on a Linux vm with docker. I'm having issues with Port 25 being blocked and so the SMTP server is unreachable, so the server is not sending or receiving emails. I want to know if there is another way I could configure the server such that I can get around the SMTP server only being available thru port 25? I also asking if there is anyone who is running their own mail servers hosted on GCP and maybe they can share their experience? Hope i'm beginning to make sense.

So what are the issues you are having?

Google already has an email service, that's probably why they are blocking yours. try a different provider.

Google Cloud blocks SMTP port 25 egress. This prevents traditional SMTP servers from functioning. You can use other ports such as 465/587 but that is typically used to login to a traditional SMTP server (Gmail, Workplace, O365, Zoho, etc) for email forwarding.

In summary, you cannot host a traditional email server in Google Cloud. You can implement email forwarders.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
