Hello,

I have problems with mail transport from Postfix, all emails are taken as local and I get the error:

Recipient address rejected: undeliverable address: No user at this address

It was working fine, and suddenly I started to get that error.

Thanks.

To ways to potentially resolve.

One is to remove the recipient address validation cache. (best)
Another is to disable recipient address verification using eFa-Configure (under mail settings) or adjusting the postfix main.cf. (not best, but sometimes necessary, you should implement another form of recipient verification if this does not work for you)
