Exchange 2010 Sender Filter

Friday, August 31st, 2012

A customer was not able to receive email from 1 client – he would always get a error back saying:
5.1.0 Sender denied
We spent time going through the Exchange Sender AS options (which were changed from Deny to Stamp and allow) and also through the AS software that was running on the server (configuring whitelists for the incoming email) and yet it would still get bounced. They showed up in the Exchange log as arriving so there was no question they were getting to the system.
Turns out Exchange 2010 (and possibly 2007) also pulls block lists for senders from the end users OUTLOOK. So we logged into the users OWA and went to the block list and what do you know – the customer had blocked the sender ! By mistake of course… Removed their email and all fixed.

Mouse or Internet stopped working ?

Wednesday, August 29th, 2012

We had a couple of strange support cases recently – 2 where the USB function had stopped (ie the mouse and trackpad on a notebook just did not work) and another where the pc could not ping beyond the subnet.
Both occurred during normal use and in the end we tracked it down to an update in Kaspersky that seems to have caused those parts to ‘lock up’. A removal and reinstall of Kaspersky fixed the issue – it was a good chance to upgrade to the latest version too (2013). Whilst the AV software on your PC always gets updated (as long as the license is current) for Virus definitions, new versions of the actual program normally need to be done manually (and its generally worthwhile to do so – they are often faster or have new features present).
