 It is recommended to create a SMTP server name (that is the server name of LUCY). Most SMTP servers will accept your mail if you simply have a reverse DNS entry. It does not have to match the domain name on your e-mail address. Some SMTP servers will reject mail if the reverse DNS doesn't match the HELO/EHLO hostname used in the connection. If your mail server's hostname is mail.example.com then your reverse DNS, MX record, HELO/EHLO, and SMTP greeting banner should all be mail.example.com as well. According to RFC 2821 the SMTP client MUST, if possible, ensure that the domain parameter to the EHLO command is a valid principal host name (not a CNAME or MX name) for its host. If this is not possible (e.g., when the client's address is dynamically assigned and the client does not have an obvious name), an address literal SHOULD be substituted for the domain name and supplemental information provided that will assist in identifying the client. An SMTP server MAY verify that the domain name parameter in the EHLO command actually corresponds to the IP address of the client. You can save this under the mail Settings: It is recommended to create a SMTP server name (that is the server name of LUCY).

-  * 1) You know that the SMTP communication works and LUCY's IP is not filtered by any 3rd Party product. Therefore you experience a configuration issue in the campaign which causes the mail to get filtered (like using a spoofed sender domain which has an SPF record, using a sender domain that points to a different MX record or has no valid MX record at all or creating a campaign that gets filtered because of the SPAM score). Also make sure you even created a [[:mail_settings|message template]] in the campaign). If the test mail does not go through: make sure port 25 is opened on your router/firewall and mails do not get filtered by SPAM filters. In case the firewall configuration is not allowing LUCY to send mails, you might also configure LUCY to use an external mail server. See [[:using_an_external_mail_server_or_web_proxy]].+  * 1) You know that the SMTP communication works and LUCY's IP is not filtered by any 3rd Party product.
