Accounts moved to new server cant retreive mail

[4u123]

Hi,

I just moved a load of accounts to a new server and everything is fine except that some of them cant retreive their mail via pop3.

Their mail client logs in ok and there are no errors but no mail comes down. They can see new mail if they use webmail.

I got one to remove the mailbox and re-create it and this resovled the issue but I'd rather fix it than get them all to do that.

I've run the mailperm script and thats not had any effect.

/scripts/courierup --force fixed this.
