Hello Team,
I have RTIR 4.4.4 installed, have installed and configured msmtp as follows:
defaults
logfile /var/log/msmtp.log
account default
host myorg.mail.protection.outlook.com
port 25
user mail@my.org
password P@ssw0rd
from mail@my.org
When I try sending mails using msmtp using the above configuration:
-
To the mails on the same domain I get the error
<-- 501 5.1.3 Invalid address [DB8EUR05FT044.eop-eur05.prod.protection.outlook.com] msmtp: recipient address undefined not accepted by the server msmtp: server message: 501 5.1.3 Invalid address [DB8EUR05FT044.eop-eur05.prod.protection.outlook.com] msmtp: could not send mail (account default from /opt/rt4/etc/msmtp_wrapper.conf) -
If I send to other office365 mails I get the error
<-- 451 4.4.62 Mail sent to the wrong Office 365 region. ATTR35. For more information please go to https://go.microsoft.com/fwlink/?linkid=865268 [AM6EUR05FT052.eop-eur05.prod.protection.outlook.com] msmtp: recipient address othermail@office365.com not accepted by the server msmtp: server message: 451 4.4.62 Mail sent to the wrong Office 365 region.

To gmail mails and other mail servers
550 5.7.64 TenantAttribution; Relay Access Denied [VI1EUR05FT045.eop-eur05.prod.protection.outlook.com] msmtp: recipient address mail@gmail.com not accepted by the server msmtp: server message: 550 5.7.64 TenantAttribution; Relay Access Denied [VI1EUR05FT045.eop-eur05.prod.protection.outlook.com] msmtp: could not send mail (account default from /opt/rt4/etc/msmtp_wrapper.conf)
The msmtp command am running is:
$ echo "RT msmtp test" | sudo msmtp --debug -C /opt/rt4/etc/msmtp_wrapper.conf mailadrress@beingsent.to
Any insights on how to go about this will be super helpful and highly appreciated.
