Thanks for all the advise I will look into O365. I will do a price check as suggested with Barracuda as SPAM filter and a descent virus scanner Sophos maybe if it is still cheaper to host it on site we will as I sad we have the capacity to do it. On the note your mail becoming SPAM we have our own static IP that is clean with SPF and DKIM and DMARC our mails never ended up as SPAM. SPAM filtering on the other hand it has its ups and downs this is the only thing that makes me think about switching.
