Email issues... websitewelcome.com COMODO RSA not trusted

[crashtackle]

Morning all...

We have suddenly developed an issue when sending email from a range of devices - iPhone, PC, macs... we get a series of 'not trusted' error messages when sending email only - mail is receiving as normal. Mail has been working fine for years, until 3 days ago. Hours chatting to support has proved fruitless (as expected).

Iphone screen shot below... notice there is no 'Trust' override button... just flat out rejects it.



Does anyone here have a solution or some advice? Would be hugely appreciated.

Thanks!

also, the domain health check at mxtoolbox says the domain is blacklisted

I think this has to do with google's mail servers. I've checked with 3 of my clients now and all of them are blacklisted.

Mainly on aspmx.l.google.com and alt1.aspmx.l.google.com

I'm hoping to get some feedback
