Hi all,

I've been cracking my head for the past few nights trying to resolve this issue.
Whenever i send an email to a certain org, i will get a SSL verify error below. I'm sure the email is not delivered because if it is, there will be an auto reply. This works when i send using gmail.

[103.3.200.110] SSL verify error: depth=0 error=self signed certificate cert=/ST=CA/L=CU/O=TREND/OU=IMSVA/CN=IMSVA.TREND
[103.3.200.110] SSL verify error: certificate name mismatch: "/ST=CA/L=CU/O=TREND/OU=IMSVA/CN=IMSVA.TREND"
SMTP error from remote mail server after MAIL FROM:<[email protected]> SIZE=484398: 451 4.7.1 <[email protected]>: Sender address rejected: Service temporarily unavailable; SPF check failed and transaction closed due to the organization's policy.

I reloaded all my SSL certs using the directadmins Lets encrypt, did a few checks with online SSL checkers which passed all aspects of the SSL config.

Any idea?
