Sending attachments gives error 816 - invalid arguments

[jhv...@gmail.com]

I'm using Mailsend version 1.17b14

I'm able to send an attachment when the file resides in the same folder where Mailsend executable is (-attach "pricelist.pdf").

But when I use a path in the file name (-attach "d:\temp\pricelist.pdf") I get:

Error: smtp.c (816) - Could not open file for "d:\temp\pricelist.pdf" reading (Invalid argument).

I've also tried the 'mime-type' syntax ("pricelist.pdf,application/pdf,a") but that doesn't work either.

The entire command string is:

D:\smtp\mailsend.exe -to externaladdress -from internaladdress -sub "TEST EMAIL13
MAR 2014_09:58" -starttls -port 587 -auth -smtp mysmtpserver.com -user
internaladdress -pass xoxoxoxo -attach "d:\temp\pricelist.pdf"

I obviously changed addresses, servers & password for this posting.

My goal is to create a basic program that creates & executes the SendMail command so I can automatically send my customers their invoices via email.

I'll appreciate any guidance on this.

If you are calling mailsend from another program, you have to escape back slash e.g.  "d:\\temp\\pricelist.pdf" or use forward slash, e.g. d:/temp/pricelist.pdf

Thanks.
