Re: Bug in SMTP methods in 4D Internet Commands plugin
Spam filter on the receiving end? Maybe try sending to a different address, preferably in a different email domain.

It fails using a brand new database, on two different machines, on two different networks, connected to two different SMTP servers. In 30 years of 4D development, this is the strangest issue I’ve seen. Thanks for testing it out. I figured it couldn’t be an IC plugin bug, but everything I saw pointed to that. Oh well - it’ll be fun finding out what it really is.

RE: Bug in SMTP methods in 4D Internet Commands plugin
Ben
I just tried this out with your code below.
Received both emails including: " Invalid subject containing changed by"
So...
Something else is hokey-pokey.

Subject: Bug in SMTP methods in 4D Internet Commands plugin
I've discovered a bug in the 4D Internet Commands SMTP methods. If the message
subject contains the text "changed by", there won't be any errors returned but
the e-mail will not be sent.
I've tested it on the following versions, all running on macOS 10.13.6
* 4D 16.3HF4 64-bit, 4D Internet Commands 16.3 build 16.224100
* 4D 16.4 64-bit build 16.226553, 4D Internet Commands 16.4 build 16.226553
* 4D 16.4 32-bit build 16.226553, 4D Internet Commands 16.4 build 16.226553
* 4D 17.0 build 17.225365
I've also tested it running under Windows server.
I've tested it on different machines, using different SMTP servers, on
different networks. Same result. I find it hard to believe that having "changed
by" in the message subject would cause the e-mail to not be sent, but my
testing shows otherwise. Still, I've enclosed a small method below, and I'd
appreciate it if others could try it out and let everyone know the result
(you'll need to set the variables for the STMP server, addresses, and
username/password if your SMTP server needs authentication).
This is a weird one. I'm assuming it's caused by some old debugging code that
was left in place, but who knows.
Thanks,
Ben Kershaw
