Getting hit quite hard with zip file virus's, dodgy emails with .doc attachments, invoice and delivery notifications.

What would you recommend to deal with them, either on the server or an upstream smtp filtering service.

Server is Exchange 2010
 
Gfi maxmail is quite a good upstream filter and not overly expensive.

That way you can also lock down your exchanges from external access.

Agreed. Filter the mail before it gets to you. Loads of options out there to choose from: GFI (as mentioned), SpamHero, ExchangeDefender etc. These services receive mail for you and pass on clean mail (domain MX records point directly to the service rather than to your mail server).

You can then setup your firewall to only accept mail on port 25 from the service. Added bonus is that most of the mail filtering services will spool mail for you if your Exchange goes down for whatever reason (loss of connection etc.)
 
We use Mimecast which works well for us and as said before simply lock down inbound and outbound SMTP to specific IP ranges.

Mimecast isn't the cheapest though!

Yeah, GFI also lets users on to read their queued email too in that event. I imagine some of the others will too.
 
Looked at Mimecast - good bunch of people, great product, but expensive.

We've ended up going for iCritical. For filtering their offering matches Mimecast and their support has been excellent up to now - 100% UK based and straight through to someone who knows what they're doing.
 
Not sure how their "cloud" stuff is but we had nothing but trouble with GFI managed antivirus for our servers and PCs. Ended up ditching the it consultants who insisted we installed it and going back to Sophos.

We use mail marshall as well which works very well.
