If you cannot use your email server or the server of your email address provider to send out emails from your LiveAgent account, there is an option to use LiveAgent servers too.
Note that this option is not preferable and not recommended. Because of servers shared with other customers, there is a higher risk of your emails being marked as spam or even directly blocked by various mail providers.
It is always recommended to connect outgoing email accounts via the Google/Microsoft connectors, or via the SMTP method at first.
In your LiveAgent account, navigate to Configuration > Email > Outgoing Email Accounts, and click on the "Integrate new email account" button.
In the right "Use LiveAgent mail servers" section, click on the "Integrate" button.
On the next screen, insert the email address you want to set up as an outgoing email account and click the "Integrate" button again.
On the final screen, you can see instructions needed to set up the SPF record in your domain settings. Setting up an SPF record in your domain can be done in the DNS settings, specifically in the TXT record. This record authorizes LiveAgent servers to use your email address to send your emails. The way how to add the SPF record differs based on whether you already have some v=spf1 record set for your domain or not. If you don't have any other SPF record configured for your domain in your domain management panel, then you have to create a new TXT record like this:
v=spf1 redirect=mail.mycompany.ladesk.com
If you already have an SPF record created in your domain management panel, for example, your current SPF record looks like this:
v=spf1 a mx include:_spf.websupport.sk -all
then you need to include the LiveAgent record in it, so your existing record ends up looking like this:
v=spf1 a mx include:_spf.websupport.sk include:mail.mycompany.ladesk.com -all
If you are unsure where or how to create/adjust the SPF record, please contact your server admin or server hosting support to set it up for you. After it's set, you can check whether the SPF record is set correctly with an online checker tool. It might take up to 24 hours for this change to propagate.
Do not forget to replace mail.mycompany.ladesk.com with the real domain name of your LiveAgent account.
Click again on the "Integrate" button, and the system will try to verify the proof of ownership of the email address and if the SPF record is set up correctly. After successful verification, finish up the connection process.
