email verification can be sent to my yahoo (or gmail), but no show up in inbox/spam

[europacafe]

I installed it on my Debian VM running on my Unraid server. I can sign up with my yahoo mail, but the verification mail never showed up in my inbox or spam. Resend also didn't show up. This is the mail.log section showing yahoo accepted the mail

``Dec 9 09:36:03 xxxx-unraid postfix/smtp[1589057]: 12E0AA191B: to=<[email protected]>, relay=mta5.am0.yahoodns.net[67.195.228.106]:25, delay=3.1, delays=0.24/0.01/1.9/0.91, dsn=2.0.0, status=sent (250 Ok, message accepted for delivery)Dec 9 09:36:03 xxxx-unraid postfix/qmgr[1133413]: 12E0AA191B: removed``

I also tried with my gmail account and got the same result.

Here below is part of the postfix log after it started. I'm not sure they are the log messages which are supposed to be:
