I can rececive emails, but cannot send any emails

Hi,

I installed an CWP panel on Centos 7 and have CWP pro version.
I created several accounts and then moved on to create an email account.

I am able to receive emails, but I cannot send out any emails. All remain in the mail queue.
I checked all the recommended ports and the are open and listening.
setup is:
Posfix
spf1 staus ok
DMARC status ok
KeyTable sttus ok
TrustedHosts status ok
DKIM1 not able to enable

Can someone help me please?

Thanks,
LJ

DNS correct with an MX record in place? Verify with dig.
CSF firewall set with SMTP ports (25, 465, 587) open?
Are you starting without Clam and Amavis and SpamAssassin in the mail transport chain for simplicity?

re fix the spf record ...


re build the mail server
with opendkim on


check your ssl


and try to sent email to mail-tester.com .. not to gmail if you test sent email to gmail... you need "all green"
