Dear Maintainer,
when importing contacts from a vCard file, any vcard object that
contains an e-mail address whose domain part is a nonexisting domain
(presumably identified by an NXDOMAIN reply from DNS), the vcard object
is silently ignored.
Example (note that vCard mandates CRLF as newline sequence):
---
BEGIN:VCARD
VERSION:3.0
N:Doe;Jane;;;
FN:Jane Doe
EMAIL:jane.doe@example.invalid
END:VCARD
---
I would expect that the vcard object is successfully imported as a
contact. Alternatively, I would expect an error or warning message
indicating that some contacts failed to import and why.
Note: Creating or modifying a contact via the Roundcube web UI to have
an e-mail address with a nonexisting domain fails with the error message
"Invalid email address: [...]".
