We've used SendGrid in the past as a fail safe when we've been
blacklisted. If you keep having issues it can be worth using a
similar service and let it be someone else's problem (although this
obviously depends on your SLA and responsibilities).
Do you know if Symantec Email server share spam reports and similar?
If you're getting blocked by more than one it could be due to email
content rather than things at the domain level as Martijn pointed
out.

Thanks Ben the RBLMon is already useful, automation of
checks is very handy.
With SendGrid do you use that your primary or backup email
provider?
The servers are not blacklisted not according to RBLMon, so I
concluded its a case removing the IP blocks.
It appears to be targeted by recipients using Symantec Email
server.

of the logs on the server). This can be a useful to have waiting
in the wings should such a situation occur.
