Direct login for Webmail
What login details do I use to access Webmail?
If an email address is linked with multiple email mailboxes, you must log into Webmail with the specific mailbox. The email address required to log into Webmail is the combination of the mailbox name and server name, for example: webXpY@lx#.hoststar.hosting (The first letter of the server name is a small «L» like Linux. Replace «#» with the «effective server number of your hosting».).
The name of each mailbox is listed in the table view of My Panel.
The server names, for example, are found in My Panel (My Panel login), under «Mail» → «Webmail».
The username for logging in is the email address.
If an email address is linked with only one mailbox (visible in the tables view), you can use this email address as the username when logging in.
If you are unsure which email address is the username, check under My Panel (My Panel login), «Mail» → «Email addresses».
