Your MailServer will be installed immediately after your order and can be configurated by yourself according to your needs.
You can do the configuration of your Xchange servers (e-mail) in your System Configurator where you can configurate the following functions:
The login for your System Configurator can be found on WEBLAND.CH. Detailed online help are available in your System Configurator.
Before you can send and receive e-mails, you must install the requested Xchange accounts (e-mail) in your System Configurator (see above).
Principally, you have two possibilities to send and receive your e-mails:
1. Register yourself in the Xchange Web Access Login window under WEBLAND.CH: Enter your e-mail address in the format "felix.muster@yourdomain.ch" and your password.
If you wish to save your registration data and only to click the "open" button on your next visit without having to enter your login data again, then activate the "reminder" check box (note: to be activated only on computers to which only authorized persons have access!).
If you wish to establish an encrypted SSL connection, activate the check box "SSL".
Then click on "Login".
Now you find yourself in WebClient "Xchange Web Access" where you can send and receive your e-mails and edit appointments, tasks and notes.
A detailed manual for the operation of Xchange Web Access is available under Point Help or under the following link Manual.
2. You are using an e-mail program like, for example, MS Oulook. All you must do is to make some configurations in your e-mail program and you can immediately make use of your personal account. Under the register Mailprograms, you will find detailed instructions, on how to install your e-mail account in the respective program.
How it works
When a SMTP server is contacted to receive an e-mail, the following data are known to this mail server before the mail server accepts this e-mail:
Sender’s e-mail address
Recipient’s e-mail address
If a Webland mail server has not received an e-mail with this combination of addresses before, the delivery attempt will be blocked by the SMTP server with the message that a temporary error has occurred. The sending mail server is thereby prompted to send the e-mail again.
Message: 450 4.7.1 Recipient address rejected: Greylisted for 90 seconds
Any attempt to send an e-mail with the same configuration of data will be accepted now (which a SMTP server configurated according to the RFC standard specifications must do in any case). If and when a new delivery attempt is made depends solely on the sender or on its mail server configuration.
Webland has no influence on the configuration of external mail servers. In exceptional cases, however, there is a possibility to exclude certain mail servers from greylisting (IP-Whitelist). All mail server IP addresses of known ISP's (e.g. Bluewin), for example, are included in the so-called "Swinog Whitelist".
For requests for the inclusion of mail servers (with a fixed IP address) in the whitelist, please contact our technical department. For technical/administrative reasons, however, we must restrict ourselves to generally problematic and high-volume mail systems.
Advantages
Software typically used for sending mass e-mails (particularly worms and trojans) do normally not try to re-send (spam) e-mails to the same SMTP server. Such e-mails are successfully filtered out through "Greylisting".
"Greylisting" is a very effective method for spam elimination which reduces the amount of spam e-mails by up to 90%.
Unlike heuristic spam elimination processes, "Greylisting" ensures that, ideally, no e-mails get lost.
Disadvantages
The negative effect of Greylisting is restricted to a delay of usually 1 to 5 minutes in the delivery of e-mails (depending on the moment when the sending mail server tries to re-send them).
The negative effect is restricted to the first e-mail of a sender/recipient combination. The sender/recipient combination will be stored in the database for 60 days.
Any re-sent e-mail of the same sender/recipient combination will get through the "Greylisting system" thanks to a database entry.
It must also be noted that, in principle, there is no guarantee for immediate delivery of e-mails.
Possible consequences
Some e-mail systems or their administrators do not keep strictly to the e-mail protocoles, as declared in the official "RFC standard specifications".
Incorrectly configurated systems may cause the sending mail server to reject e-mails and to refuse to re-send e-mails so that wanted messages get lost.
Unfortunately, Webland has no influence on the (incorrect) configuration of external mail servers.
In this case the sender of the (rejected) e-mail must contact his mail server administrator and point him out to the incorrect configuration with the key word „greylisting“ to make him correct the error.
As a "temporary solution", the e-mail can also be re-sent by the sender.
Webland puts many mail servers (primarly those of big providers like Bluewin, Sunrise, GMX) on a whitelist to prevent that these e-mails are affected by greylisting.
Note
Some mail server programs would generate a delivery report to the sender on the very first attempt to send an e-mail rejected by greylisting. As often as not, this report is not given much attention and thought to be a report of a definitely failed delivery. In fact, it is normally only a piece of information which says that the e-mail is being re-sent.
Outlook
Spam senders may try to improve their spam software to avoid greylisting (for example, by making a second delivery attempt). This, however, requires much more resources and allows to sent less spams per time unit. The more important and effective, however, is the occurrence of additional costs which will put the spammers off.
The time delay can also be used to detect spam senders and to integrate them into the spam filter.
