Where in the Exchange environment will an email not be allowed through if it does not like attachments being sent from someone, i.e. if they attach pictures from a camera. Could bed jpeg or other format as well.
User is expecting an email but can't get it because someplace the email is not allowed through because it does no like the attachments being sent. I need to fix it so it will be allowed through.

Could you please explain what SPAM appliance you use and the size of the attachement etc? Exchange will allow the mail to go through as long as its under 10MB which is the default size unless modified you can change this under:

Exchange system manager - Global - Message Delivery - Defaults

You need to first clarify if you have a SPAM appliance etc?

I would look at this arcticle, my guess is the pictures they are sending in the email are greater than 5mb which is the default size allowed through on exchange.

Hello lanman777,

this is because of the CEICW attachment blocking, the attchments can be found under that folder too.
If you want to disable that blacking, rerun the CEICW and uncheck 'attachment blocking':

If you re-run the connect to the Internet wizard, there is an option to strip various attachments in the wizard.  It could be that this is where your attachments are getting removed.

By default SBS/Exchange has numerous extensions it blocks. You can locate and edit this by running the Configure E-mail and Internet Connection Wizard. This is located under Server management | Internet and e-mail | connect to the internet. Run the wizard, do not make any changes until the last screen which will provide a list of blocked attachments you can edit.
