Exim does the routing steps, and if these routing steps succeed, the address is verified. > so is there a way for Exim to send a VERIFY ACCOUNT message to the sender? There is no such message. I think, they use this term to describe the process… Exim is capabable of doing "callout verification". (They use this term too, and they use Exim too at their primary MX.) In your ACL setup you'll see some line require verify = sender This checks the sender, roughly by doing "exim -bvs …" If you change this line to require verify = sender/callout you'll get the callout feature. But be sure to read about the callout options and implications. Somebody could put tons of mails (fake) originating from *@t-online.de. T-Online uses some ratelimit for incoming connections, thus, you'll be unable to send messages to T-Online for a while (typically 24h), because of your high connection rate doing the sender verification callout. We use require verify = sender [ bunch of other checks ] require verify = recipient/callout=defer_ok,use_sender require verify = sender/callout=defer_ok [ bunch of other checks ] But even if you put these ACL in place, you still can't verify the address with "exim -bvs", you need to ask for processing the callouts: read about -bh, -bhs and try "swaks --pipe 'exim -bhc ..'"
