I am using smtp zohomail to sent email confilmation for my forum ok till now but when i add site to cloudfare nothing email send,it`s show error on error log : can not open socket, i am try to not using cloudfare,email still sent ok,is that cause by firewall cloudfare? Or any reason?
Help me please,thanks

That’s usually because the DNS record for your SMTP/POP/IMAP server is :orange:. It should be :grey:.

You mean i must change yellow cloud to black? But i am not add any record smtp,pop,imap at cloudfare,just add at root domain,is that i must add smtp,pop,imap sever to cloud fare and change yellow cloud to black?

All of your DNS settings need to be added here. That includes MX records and whatever Zoho tells you to use for SMTP/POP/IMAP.


Every time i add this to cloudfare ,it`s show this error,can you help me fix ?thanks

I believe that is a known issue on mobile, try adding the record on a pc or choosing ‘Desktop site’ in you mobile browser menu.

Your MX records look okay, you probably cant connect with your client I presume.
