Handling SMTP's "554 Too many nonmail commands"

[aularon]

Hello,

There's a problem with some mail servers (I am using name.com's) when sending too many NOOP, here's the debug output:

CLIENT (DATA) 1:
└──------Nodemailer-0.6.3-?=_1-1399044830098--
SERVER 1:
└──250 OK id=xxx-xx-x
Sent: 250 OK id=xxx-xx-x

└──250 OK
CLIENT 1:
└──NOOP
SERVER 1:
└──250 OK
CLIENT 1:
└──NOOP
SERVER 1:
└──554 Too many nonmail commands

After that, all subsequent emails are not sent, no errors no nothing, the transport fails silently.

Thanks for the useful module :)

This was a bug, NOOP errors were not handled properly. This was an issue with underlying simplesmtp module, not Nodemailer itself. You should remove Nodemailer and reinstall it, if you just try to update Nodemailer, the simplesmtp dependency is probably not updated
