To allow your Gmail account to be used to send and receive e-mail from the Infradox webservices (e.g. to receive order notifications, to send registration e-mails and so on) you will have to make a few changes to your account.
Note that using Gmail is possible if you don't have Gmail for Domains, but then your clients will receive e-mails from a gmail address (for example email@example.com). You should get a Google Apps account with Gmail for Domains and then you should create a separate mail account that will be used by your website only. With Gmail for Domains your clients will receive messages from the webserver with your domain in the sender address. For example firstname.lastname@example.org.
Once you have created the Gmail account that you want to use for the web server messages:
1) Log in to your Gmail account at https://mail.google.com
2) Click the icon on the top right to open the pull down menu and click Settings
3) Click Forwarding and POP/IMAP and make sure that Enable POP for all mail is enabled and that IMAP is enabled.
4) Save your changes
5) Now go to this URL: https://www.google.com/settings/security/lesssecureapps and make sure that Access for less secure apps is turned on
Once you have done this and you have tested that you can both send and receive mail with the account, you can create a ticket that must contain the login and password of the Gmail account. We will then change the SMTP settings on your webserver.
Note A) that we will stop e-mail hosting shortly but we will keep our mail server running for websites messaging only - until all of our clients have Gmail up and running and B) if your e-mail is already hosted elsewhere (not by Xpertise) and you don't want to use Gmail, that is also possible. In that case you'll have to tell us the details of the mail account you want us to use (mail server address, login and password).
Why use Gmail instead of Xpertise mail servers?
Gmail offers the best possible availability. By using Gmail you'll be able to send and receive mail always, even if our connections or servers are down. Also, by configuring the Infradox web services to use a Gmail (or other mail server) account, you'll have more control and you'll be able to access all sent messages. That includes the automated messages that were sent by the web services.
