For pipes in Julia, you explicitly need to use `pipeline`, `<`, `>` and `|` don’t work in commands yet, like they do in Bash. You probably want:
```julia
sendEmailCmd = pipeline("testEmail", `sendmail -t`)
run(sendEmailCmd)
```

Thank you, it works.
Is there a way I can replace the file testEmail with a string composed in Julia ?

Yes, you can use an `IOBuffer` in the `pipeline` like so:
```julia
message = """
To: myTestAddress@gmail.com
From: myFromAdress@myServer.org
Subject: One-line subject
This is the content of the email."""
sendEmailCmd = pipeline(IOBuffer(message), `sendmail -t`)
run(sendEmailCmd)
```

uhg, I got a MethodError…

"To: myTestAddress@gmail.com\nFrom: myFromAdress@myServer.org\nSubject: One-line subject\n\nThis is the content of the email."

That does seem odd. Could you try if
```julia
run(pipeline(IOBuffer(message), `cat`))
```
works on your machine? What is your os, maybe the output of `versioninfo()` can give some more clues. If you’re running Julia 1.0, it may be the same as [this](https://github.com/JuliaDocs/DocumentationGenerator.jl/issues/2) issue. Does
```julia
pipeline(`sendmail -t`, stdin=IOBuffer(message))
```
work?

Yes… I was looking as well… I think this has to do with [this feature request](https://github.com/JuliaLang/julia/issues/15479) implemented on master [in this merge of 7 Dec 2018](https://github.com/JuliaLang/julia/pull/30278), so it should works on recent Julias, but I have 1.0.3.
`pipeline(`sendmail -t`, stdin=IOBuffer(message))` has been merged in February 20189, so it also doesn’t work with Julia 1.0… ok, I’ll update Julia on the server…
UPDATE: I can report the suggestions given by @ [simeonschaub](https://discourse.julialang.org/u/simeonschaub) (i.e. `sendEmailCmd = pipeline(IOBuffer(message), `sendmail -t`)` or `run(pipeline(IOBuffer(message), `cat`))`) works with Julia 1.1 (but not with Julia 1.0.4). Thank you again.

Hi,
Jumping in on this thread.,
Is there a nice way to encode a graphics file and send it as an attachment with this library?
Thanks for any pointer and best wishes
Eric

There are multiple ways to do this proposed in this StackOverflow thread:
[https://unix.stackexchange.com/questions/223636/sendmail-attachment/223650](https://unix.stackexchange.com/questions/223636/sendmail-attachment/223650)
I would just check, if any of these proposed alternatives are installed on your system.

Thanks @simeonschaub!
Yes, I was wondering if there was a higher level way than the method referred to here.
So will build up the base64 and separators and send with `SMTPClient.jl`
🙂
