SMTP sender verify and remote greylisting

Hi, using 7.500.

Should our use of the ASL sender verification work with remote sites that greylist? My understanding is that the sender verification results in a call out that tries to issue a bounce message to the remote sender?

A sending site is reporting that we're blocking their mail with an admin failed message (haven't yet seen a sample).

On the local logs, Mail Manager shows 'rejected: spam (confirmed)'

The detailed log shows an attempted callout, then a few transactions later, the message id logs an event containing name="email rejected".

When I telnet to the remote host on 25, it'll accept mail from <> for the user, then drops the connection with a greylist message.

So, does the sender verification still use a bounce attempt in v7, and if so, will it retry / otherwise cope with the remote host greylisting the attempt.

Thanks

I looked for the why, but have found the change in log format from v6 to v7 requires a bit more reading.
