List emails not coming through

Hi all
The lists I am an admin for (different account) have stopped working today. Emails send quite happily and go into sent folder from multiple emails on the list, inc admin. No bounce messages. But nothing is arriving. This is multiple lists but all made by one user. I've tried sending a password reset as advised in the FAQs and it came through straight away. What can I try next Not sure where I should be looking!
Thanks

this is more than had before- do we just need to wait?

There was a problem with our virus/spam filtering that was delaying things, it's fixed now and catching up.
If this persist on the next days let us know please.
