Please unblock port 25 (allow outbound mail connections)
This is of course already addressed in you documentation, but as far as we're concerned the given answer is inappropriate for us. We do not wish to spam anyone, send mass emails, or abuse the system in any other way. I would expect the service to allow us the chance to prove this and not block such outgoing traffic until any actual offense takes place.
I was very pleased to have started work on your platform, but this single issue is likely to force me to search for a different provider.
We are currently testing a new option that may help people send mail without using a third party service. If you are interested in testing this product, please fill out the interest request form here1. Product Management for the feature may reach out to you.
We are also continuing to make improvements to our system to allow for some customers that have an established relationship with us to apply for an exception to be able to send directly on port 25. There are a number of IP reputation issues that have to be worked through for such a use case, so it should not be considered a common solution that will meet everyone’s needs.
We will have more updates on both of these items over time.
the 3rd party services to relay email are not reliable: there shared IP adresses are blacklisted, email get rejected (E.g.: spamcop backlists sendgrid probably because of other bulky email service making use of the same IP). Some email relay do have the option dedicated IP but this is too costly.
GCP shall understand that there are professional hosting provider running their business on their cloud, we know our business and we never had issues with our port 25, we control outgoing traffic and automatically block spammers.

@ Jay: The answer is obvious. You should do what I did. I have no problems sending any e-mail from my servers. It works great.
Anyy news or updates about this?
Quick fix or recommendation?
+1 please unblock it!

I don't have any trouble sending e-mail from my 2 servers. :-)
Finally here, after spending a few hours looking at why emails are not going out. what a shame ;(
Is er any update or news on the proper solution?
We urgently need to use port 25 as well for sending mails.
If all SMTP requirements are met (SPF, DKIM, DMARC, and reverse DNS lookup), then sending mails should not result into reputation problems.
Also, if a customer commits for a period of time in using a source ip address, this will only affect this particular ip addres, not other addresses.

25,465,587 portun kapalı olması ve bu kadar sürede herhangi bir çözüm sağlanmamış olması çok kötü bir durum. AWS harika bir çözüm olarak görünüyor. Bir de google'nin 3. parti uygulamalara çözüm olarak yönlendirmesi ise tamamen saçmalık. Neden bu kadar emek verip mail göndermeden sunucu kullanayım ki?

"We will have more updates on both of these items over time."
I guess this is talking about all of the full expanse of time on a galactic scale, since there have been no "updates" to this in almost two years. By the way even your link goes only to a disabled form page. Disappointing... and expensive!

Dear Google! this is how i feel about port block and restrictions. "I bought a brand new BMW car from their showroom but they delivered me a car without a engine. Now to use it i have to buy a engine separately" What is the point of $300 if We can't use their service completely without any restrictions and port block. By blocking ports we have to use other smtp relay service. That means unwanted expense. Please fix it.

This is a complete joke. Google does not care for proper SMTP implementation. It's the way how Google handle things, if you aren't using it's services they just block it.
This is unacceptable

4.4 years and 700+ votes and still worlds largest ESP can't open Port 25 to make a connection between servers.
What's the use of $300 credit GCP throws to me?

Just created an instance and was working on it in this lockdown phase. was tuning it up one by one. But stuck on webmail. Got lot of knowledge by googling and always thought i am more closer to the solution. At last I fall in here. I was planning to shift all my client from hostgrator anf godaddy in my own server and was very excited too. Google will not give you this facility as they want you to use gsuite and pay again...... :)
I’m one of those people who spent a couple of days setting a webmail server just to find that the port 25 is blocked. And from the admin comments (one every two years) I guess that this isn’t changing any time soon. I will then stay with ovh.com
I can only imagine the number of people that have wasted time setting up their email servers and tried to fix something that is set up not to work. Imagine also assuring/promising your clients you could create it for them. Unbelievable!

Paul Nash seems to have jumped ship to Azure. Also, the Cloud Mail product (or at least the Alpha) was cancelled.
Could anyone from Google provide an update as to what we can expect here?
I'd like to move services into GCP and being able to request an exception for port 25 outbound traffic would be highly appreciated. Not everyone is a spammer, there are legitimate use cases too.

Both AWS and Azure block 25 but upon providing details of need will open. I know coz I just did it recently as a project to compare VPS/Elastic compute providers. Google fail.
I have migrated my critical account which require mails to be working on VMs. Suddenly every thing is working except emails.
I require port 25 unblock to make this possible. Else i will not be left with any option but to switch to AWS. Cant let people hung on for this reason. I doubt port 25 block is that nuisance GCP cant handle with good security measures?
