I honestly don't know why I thought that there wasn't a list_to_binary function...I suppose thats what you get for programming late into the night. I believe it was on How I Met Your Mother that I heard the phrase "Nothing good ever happens after 2am." I should probably take that to heart when it comes to coding.<br><br>> Date: Sat, 14 May 2011 23:28:12 -0300<br>> Subject: Re: [erlang-questions] Odd behavior when sending emails via SMTP when messages are converted to/from binaries<br>> From: juanjo@comellas.org<br>> To: silent_vendetta@hotmail.com<br>> CC: erlang-questions@erlang.org<br>> <br>> Yes, the correct thing to do would be to use list_to_binary/1 and<br>> binary_to_list/1.<br>> <br>> It might be possible to avoid the conversion altogether if you're<br>> writing the result of the conversion to a socket or a file.
