Recipient address rejected due to automated recipient verification

[ruanbekker]

Found the same behavior as:

• https://forum.efa-project.org/viewtopic.php?t=4173

The EFA system reports the mail address at the target as non existent, but it does in fact exist.

When I disable the automated recipient verification, it works.

Can we perhaps look at this, or a way how to clear the cache?

Having an easy way to clear the cache sounds like a good idea.
