** [bugs:#1389] SMTP VRFY issued even when server doesn't support**
**Status:** open

Seems that in curl 7.37 the VRFY SMTP command fails even when a server (such as sendgrid) doesn't list support for it. Verbose output below running on rhel 6.5 linux, suspect this applies since VRFY was introduced in 7.34 too.
