SES receiving emails from all domains

Question

I created a verified identity with a custom domain mail.mydomian.com and added the following DNS records:

MX  @   inbound-smtp.eu-west-1.amazonaws.com. (Priority: 10)
MX  mail    feedback-smtp.eu-west-1.amazonses.com. (Priority: 10)
TXT @   v=spf1 include:amazonses.com ~all
TXT mail    v=spf1 include:amazonses.com ~all

I configured SES with exim (Cpanel):

Section: AUTH

ses_login: 
driver = plaintext 
public_name = LOGIN 
client_send = : username : password

Section: TRANSPORTSTART

ses_smtp: 
 driver = smtp 
 port = 587 
 hosts_require_auth = * 
 hosts_require_tls = *

Section: PREROUTERS

send_via_ses: 
 driver = manualroute 
 domains = ! +local_domains  : ! +manualmx_domains
.ifdef SRSENABLED
 # if outbound, and forwarding has been done, use an alternate transport
 transport = ${if eq {$local_part@$domain} \
          {$original_local_part@$original_domain} \
          {ses_smtp} {ses_forwarded_smtp}}
.else
 transport = ses_smtp
.endif
 route_list = * email-smtp.eu-west-1.amazonaws.com;

I created a rule set for receiving email with no action.

I can send emails to any email but I can only receive emails from the verified domain so if I send an email from [email protected] to [email protected] I won't receive it. I have to send emails from mydomain.com only to receive them.

I try that because I can't forward emails from [email protected] to [email protected] because I get this error:

SMTP error from remote mail server after end of data: 554 Message rejected: Email address is not verified. The following identities failed the check in region EU-WEST-1: [email protected], DMARC Aggregate Report <[email protected]>
