I have followed this setup ( without the clamav part. For the last days it works pretty good.

After that i dont recieve email at and Other email adresses are properly working, like Gmail.

The logs are as follows:

Aug 1 19:30:27 droplet_name postfix/smtpd[24405]: connect from unknown[myip] Aug 1 19:30:27 droplet_name postfix/smtpd[24405]: B181FA5594: client=unknown[myip], sasl_method=CRAM-MD5, Aug 1 19:30:27 droplet_name postfix/cleanup[24410]: B181FA5594: Aug 1 19:30:27 droplet_name opendkim[1364]: B181FA5594: DKIM-Signature field added (s=mail, Aug 1 19:30:27 droplet_name postfix/qmgr[24398]: B181FA5594:, size=726, nrcpt=1 (queue active) Aug 1 19:30:27 droplet_name postfix/smtpd[24405]: disconnect from unknown[myip] Aug 1 19:30:29 droplet_name postfix/smtp[24411]: B181FA5594:,[]:25, delay=1.9, delays=0.12/0/0.24/1.6, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 31229B8258) Aug 1 19:30:29 droplet_name postfix/qmgr[24398]: B181FA5594: removed

It looks good (status=sent). But never receives it. DKIM and SPF are good.

What can be the problem?
