Does Gmail still allow SMTP?

Why SMTP is not working with Gmail?

I am not able to send any mails using my Gmail.

I have tried this for more than 6 months with Gmail, but still no luck.

I tried sending mail from but it is showing me that my server is not responding to that site. I have checked the connection on the IP as well.

You have to install a relay, which does basically the same as a SMTP server. Google Mail doesn't support SMTP directly, so you need to setup a relay. There are a few out there, and they work fine for the most part.

There are also free alternatives like SendGrid.

Does Gmail still allow SMTP?

I'm a long time Google Apps user, but I also enjoy experimenting with my own email server.

Recently I discovered that Gmail apparently supports SMTP and that it's possible to receive emails using your own email address and send them on their behalf, so I went ahead and tried sending mail directly through gmail. That went fine but I can't send any email through it. Sending mail always fails and I don't see any errors. Any idea what's wrong?
"Can you send an email to this address?". The answer to this is: Gmail can no longer read and approve the message for you if sent through the SMTP ports. For example, your messages are going out as "From: name@yourdomain.com" instead of. "From: name at domain.com" If your ISP/domain does not allow SMTP through port 25, then port 587 will still work just fine. For reference, port 587 is less likely to be blocked than port 25.

You need to create a new Gmail account that specifies which ports it uses for sending email. This is not a good reason for Gmail to stop supporting SMTP. :)
Also, note that even though this works (as you've seen), your ISP might still block you from sending to the old gmail account. If you want to ensure sending email successfully with your new domain, you should send some other email addresses to your gmail and test each one as appropriate. The process of setting up your domains with the gmail.com service does change how your gmail will behave.
