Wed/Thur last week my host performed a box migration, which caused a short period of down time, this I have no problem with.

Unfortunately shortly after the migration the server status page has been showing a DDOS attack. I can access all sites hosted on the main domain, sub-domains and add on domains, but I have no access to any email accounts on the host, these just time out.

I raised a ticket Monday of this week and the response I got was that the DDOS was being addressed and should be resolved shortly. As of today nothing has changed and I still do not have email access. I will be raising another ticket with the host but I need to know if they are giving me a load of bull about the DDOS and they have just screwed up the box migration.

So would a DDOS be a possible cause of the email access issue bearing in mind that all web sites are accessible?

I do have 2 computers and an iPhone that are online 24/7 and request email, could this just be an over zealous firewall not liking 3 different IPs requesting mail?

Thanks in advance.
 
Assuming that your email is hosted on the same box/ip as your sites then what they are saying is bullpoo, as regardless of service (email, web, ftp, etc) the IP stack would be flooded and unable to deal with requests.

So, are all your services hosted on the same box?

That's just not true, any decent firewall is going to have session limits per protocol rather than per IP, the mail server will be configurable with a max connections value, it's entirely possible for it to be on the same box and be forced offline while leaving other services untouched (in fact it suggests good practice and implementation if that's the case).

On the other hand, being down for that long suggests not having a clue...
 
Ok, I have made a successful email connection.

For the pop3 server I have been using mail.box360.bluehost.com up until the migration as advised by the host, I have just discovered I can access mail using mail.davidmarq.com which is the main domain.

box360.bluehost.com and davidmarq.com resolve to different IPs.
