Hi Michiel, Thank you for your very clear explanation. That fixed it. On the point of upgrading, it was not so much for this problem (if it had not been fixed easily here I probably would have trawled through the perl to sort it out myself), but rather for the additional new features alluded to in the first reply. regards Dan On Tue, 2009-11-03 at 14:59 +0000, otrs-request@otrs.org wrote:

Hi Dan,

The NotificationSenderEmail in the SysConfig is used for *notifications *that are sent out of OTRS, which is something different than regular answers to tickets.

For that, the email address associated with the *queue* the ticket is in is used. otrs@localhost is the default email address on a vanilla installation, I'd recommend you to change it to the address you'd like to use, under Admin

Email Addresses. If you'd need more addresses, add them there, and associate them with the corresponding queues under Admin > Queues.

Also, while we do release minor updates often, before using updating as a cure for all it might be wise to check if your issue has been mentioned in your release notes. For instance, for the latest release notes, see here: http://otrs.org/releases/2.4.5/
