Email took a long time to reach and send

Thanks to support, I finally had my email working.

I have enable cloudflare for my hostname domain.

I realised that it took me a long time to receive an email from gmail (i only tested with gmail) - 6 min to be exact and another one min for the gmail recipient to get my replied mail.

Is there some setting that is causing this issue?

Hello.

Probably you have a lot of messages in postfix queue or some network issues.
