SICF and 554 Transaction failed

Hi,

The email in one of our SAP clients stopped working after a recent reboot (although I can't say for sure this is the reason/related).

Sending an external email to the DEVSERVER gives the following error in the icm connection log.

ErrorCode: ICF-NF-http-c:000-u:SAPSYS-1:E-i:DEVSERVER-v:0-s:404-r:Notfound HTTP 404 - Not found

This error occurs before the email arrives in the SOIN, at first I was thinking the system couldn't find the email address and was returning not found.

An extract of the icm log below:

I can access the url using :http://DEVERSERVER.DOMAIN:PORT/sap/public/icf_info/logon_groups?sap-client=999 and that works fine, can anyone give me some pointers on what to look at next?

Thanks,
