Hi
I setup CWP on google cloud. I can receive email but i can't send emails.
I find this article https://cloud.google.com/compute/docs/tutorials/sending-mail/ (https://cloud.google.com/compute/docs/tutorials/sending-mail/). Here is mention that outgoing connections on port 25 (SMTP) are disabled, so you cannot use that for sending email programmatically.
Please suggest me best solution.
Thanks
you will need to use some other provider for sending/receiving emails
It's also stated in that document, that other ports are not blocked for email. So you could make use of those ports.
so then change port 25 to port 26 in Postfix config (master.cf -- smtpd )
