Attachment Stripping

[Chris_001]

We are having some problems with one domains outgoing e-mail attachments being stripped. I have checked this against other domains which are working fine and there is no difference. If I use e-mail archiving I can see the attachment but it is not received by the recipient, this must mean the fortimail unit is getting the attachment and stripping it? I have logged a ticket with Fortinet with no response in two days so any help would be great. Chris

Try sending that domain an email from another domain (Yahoo, Google, etc.) with an attachment and see if they receive it. If they do not, the problem may not be yours.

Hi Bob, I have tried this already and there are no problems receiving inbound attachments - only outbound ones being stripped. Our customer says this is only since they have passed traffic through the fortinet box and as I can see the attachment in the e-mail archiving I have to beleive them. Any other suggestions? Chris

I was asking if you sent them an email outside the Fortinet with an attachment. Are no others complaining?

[Chris_001]

Sorry Bob, I' m not too sure what you mean. We have other domains that go to different e-mail servers that are not having any problems. However this one domain is having problems with outbound e-mails. If I send from my domain - also one the same fortimail (different profile) to the user who reports not getting an attachement it works ok, so this proves the far end is able to receive attachments ok. I personally think they used to have this problem before fortimail but as I can see the attachment in the e-mail archiving then it proves the e-mail server has sent the attachement. Chris

OK. Big picture covered my debugging question. Maybe the far end has some setting stripping attachments from your domain.

Did you compare both Outgoing Content Profiles?

[Chris_001]

Yeah I have compared the profiles and both look the same. We are using content filtering on inbound (same as other domains). The only thing I can think of is that most of our domain use exchange but the domain in question does not however if I can see the attachment in the fortimail e-mail archiving then surely this cant be at fault. I have doe the test to several outside e-mail addresses including googlemail, hotmail and some corporates. Chris
