Hello,
This is my first post in the forum.
I am running on Ubuntu 22.04 (LTS) x64.
Let’s say my domain is mydomain.com. I have just installed HestiaCP with the default admin user:
- installed on
panel.mydomain.com - username = usernameofadmin
- email address =
[email protected]
My domain email is with Microsoft 365, and in HestiaCP I’ve configured Global SMTP Relay using SendGrid so that it sends email from [email protected]. I have also executed bash /usr/local/hestia/install/upgrade/manual/configure-server-smtp.sh.
/usr/local/hestia/conf/hestia.conf have these entries:
SERVER_SMTP_ADDR=‘[email protected]’
SERVER_SMTP_HOST=‘smtp.sendgrid.net’
SERVER_SMTP_PASSWD=‘XX.xxxxxxxxxxxxxxxxxxxxxxxxxxxxx’
SERVER_SMTP_PORT=‘587’
SERVER_SMTP_SECURITY=‘TLS’
SERVER_SMTP_USER=‘apikey’
SMTP_RELAY=‘true’
SMTP_RELAY_HOST=‘smtp.sendgrid.net’
SMTP_RELAY_PORT=‘587’
SMTP_RELAY_USER=‘apikey’
By triggering a manual backup in Hestia portal for admin user, HestiaCP sends the backup success notification from [email protected] to [email protected]. Notification email is received in mailbox of [email protected].
After I SSH into my Ubuntu server on the sudo user, let’s say I run a command sudo tail -f /var/log/exim4/mainlog, it prompt for password entry. On 2 password incorrect tries, I cancelled the login. It seems to generate an email with the following log in /var/log/exim4/mainlog:
2024-09-09 11:27:27 xxxxxx-xxxxxx-xx <= [email protected] U=usernameofadmin P=local S=641
2024-09-09 11:27:28 xxxxxx-xxxxxx-xx => [email protected] R=send_via_smtp_relay T=smtp_relay_smtp H=smtp.sendgrid.net [xxx.xxx.xxx.xxx] X=TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM:256 CV=yes A=smtp_relay_login C=“250 Ok: queued as xxxxxxxxxxxxxxxxxx”
SendGrid relayed the email to Microsoft, and of course Microsoft rejects it since there is no such mailbox [email protected]. This is what SendGrid captured:
May I know why in this case the email is not sent From [email protected] to [email protected] since Global SMTP Relay is set?
Thank you.
