Sending Account: Choose whether to use the system email server or your own email address to send email.

If you choose your own email address the guest will receive an email confirmation from your email address and you will see sent mails in your outgoing mail folder. You can use your own email service via SMTP or Mailgun, It is also possible to use both, first we will try your SMTP server and if this fails we will try Mailgun. If both fail, the mail will be sent by the system email server.

If you have entered a property Email address in (SETTINGS) PROPERTIES > DESCRIPTION replies from guests to confirmation messages will be sent in cc to the property EMail address. If you do not want this do not enter a property Email address.

If you do not use your own email, the guest will receive a booking notification from the system Email address.

The following settings are required if you use your own email address:

Email Address: This is the email address which will send email notifications.

Mail Server: This is the email server which will send your email. For example the gmail server is smtp.gmail.com.

User Name: This is the user name for your email server. This is often your email address.

Password: This is the password for your email server.

Use Encryption: This is the email server encryption setting. For example the gmail server requires SSL.

Port Number: This is the email server SMTP port. This is normally 25 but can be different. For example the gmail server uses 465.

Hotmail and other providers might  ask for authentication. Log into your Email account, check your notifications 
or settings and follow the instructions given by your Email provider. If you cannot find them ask your provider 
what you need to do to let third parties like Masterinsoft send Emails through your SMTP server.
