Are you hosting your mailbox on oracle free hosting? Maybe they are blocking it?

3

Do you mean that they would block both incoming and outgoing emails so that i would need to setup a mail relay from AWS for example ?

4

What is the domain? Incoming should to been blocked…

An update on this.

I have setup sendinblue.com as a SMTP relay so now i can send email from roundcube at mydomain.com to my gmail account and so on. But when i send and email from my gmail account over to mydomain.com i do not recive it.

I checked the Exim reject log and saw this.

2023-01-06 15:28:00 H=mail-qt1-f176.google.com [209.85.160.176] X=TLS1.3:ECDHE_X25519__RSA_PSS_RSAE_SHA256__AES_128_GCM:128 CV=no SNI=mail.mydomain.com F=[email protected] rejected RCPT [email protected]: Rejected because 209.85.160.176 is in a black list at zen.spamhaus.org

I then tried to send an email from my Outlook account and got this in the exim log.

2023-01-06 15:31:43 H=mail-am6eur05olkn2052.outbound.protection.outlook.com (EUR05-AM6-obe.outbound.protection.outlook.com) [40.92.91.52] X=TLS1.2:ECDHE_SECP384R1__RSA_SHA256__AES_256_GCM:256 CV=no SNI=mail.mydomain.com F=[email protected] rejected RCPT [email protected]: Rejected because 40.92.91.52 is in a black list at zen.spamhaus.org

What do this mean? the rejected IP is different on both. Anyone got any idea ?

7

Disable Spamhaus black list?
