Since the 8th of March 2010, Swisscom AG (Bluewin) has installed a mail filter (SMTP proxy) for all their DSL-customers. This filter now also checks e-mail from our customers and free e-mail providers such as GMX, Google Mail and Hotmail if the e-mail is sent from a Swisscom connection. As a result of the introduction of the new spam filter, e-mail that is sent with SMTP authentication via port 25 can no longer be sent. In such cases, the port setting in the e-mail program must be changed from port 25 to port 587 (standard port for SMTP submission).

More information about your E-Mail settings can be found under Mail Domain FAQ.

ISRlight is a fully fledged replacement for PostFinance's existing E-List solution for printing inpayment slips under Windows XP.

ISRlight is platform-independent (Windows, Mac or Linux) and will run on any common web browser such as Internet Explorer, Firefox, Safari or Chrome.

There is no need to install any software locally on your computer, and you can simply work with blank inpayment slips. The ISR reference number will be automatically generated and printed on the inpayment slip. There is no need to key in ISR reference numbers.

If you wish you can download a backup of the data to your PC at any time. Access to ISRlight is over a secure connection encrypted using https.
