I'm trying to send emails from Thunderbird with an GCE instance. I have signed up to sendgrid and have followed their instructions and used their settings for outgoing mail. Incoming mail is working fine but the connection to the Sendgrid server times out.
I just need to send email, I don't need Sendgrid. I just signed up as google documentation indicate this was needed to send emails within a GCE.
I have also tried opening port 465 (as I read from another solution) but without success.
Has anyone successully used an email client with a GCE instance to send email? If so, can you help with the correct setup? I'm not tied to Thunderbird.
Thanks.
