The problem is with the MailAddress class. I saw the problem with a non conventionnal email addresss when I implemented DKIM relaxed canonicalization.
MSDN documention : MailAddress Constructor (Exception FormatException) =>
http://msdn.microsoft.com/en-us/library/591bk9e8%28v=vs.110%29.aspx
By example, this address will generate a exception: check-auth-jsmith=[email protected].
I was thinking that the email address don't respect the rfc.

That is interesting. I was sending from [email protected]. Is the underscore the problem?
from dkim-exchange.
You should use the version 1.5.2 for the moment, the problem have been added with RecipientRule and SenderRule support.
I need to make the test to check if the problem is the underscore in the email address... but it's a interesting case to try.
from dkim-exchange.
I will try to reload the new version tonight and test again with a non underscore email address.
from dkim-exchange.
Sorry, I didn't receive any error with the email address [email protected]. With version of the Dkim Signer, are you using? With version of Exchange server?
But if a try to send to auth-jsmith=[email protected]...
Signing a mail item according to DKIM failed with an exception. Check the logged exception for details.

@Pro Why the .pdb file are no more locate in the release folder of each DKIM Signer version (Exchange 2007, 2010, 2013)?
from dkim-exchange.
@networkthinking Can you said me what is the email address of your recipient? The problem isn't with the sending email address.

@AlexLaroche I just added the .pdb files (they were never there :) )
@networkthinking I uploaded a new version which has a fallback and doesn't throw an exception, if the email address is invalid. Can you please try the new version and post the error message.
To install it copy the .dll AND .pdb to your server (the .pdb gives more debug infos).
from dkim-exchange.
@networkthinking Btw: you can check the version by Right click on the .dll -> Properties -> Details -> File Version
from dkim-exchange.
1.5.2.0 from 1/18 is working fine
Should I just download from the home page or someplace special?
from dkim-exchange.
Work for me... The exception is catch a new entry is created in the eventlog.
Couldn't parse to address: ' "[email protected]" <[email protected]> Ignoring recipient rule
But the email no more signed... By default, the email was signed before the rules was implemented. Is this is the desired behavior?
from dkim-exchange.
@AlexLaroche indeed, that's not correct. It should sign. Just fixed the signing. Is this exactly the error message which you got? Because it seems there's the closing '
missing? The E-Mail adress is then "[email protected]" <[email protected]>
including the newline?
Can you debug into the code and check if there's a newline.
@networkthinking You can take the current master branch: https://github.com/Pro/dkim-exchange/archive/master.zip
from dkim-exchange.
@AlexLaroche I just wrote a short app to validate the function of MailAddress. It parses the mail address above just fine... Can you tell me the exact charaters which cause MailAddress to fail?
from dkim-exchange.
May be, I remove some characters bu error when I pass the error message from eventlog. I remove some text before "Ignoring recipient rule" because it wasn't in English for sure.
The bad char is "=". The recipient email address is "auth-jsmith=[email protected]". I didn't not have time now to test your modification. I will try to get some time tonight...
from dkim-exchange.
@AlexLaroche Please post error messages by using backticks: http://superuser.com/questions/254076/how-do-i-type-the-tick-and-backtick-characters-on-windows and https://help.github.com/articles/github-flavored-markdown#syntax-highlighting
This makes sure the message is posted without missing chars
Also this email address works fine, I used the following console app to validate it:
string addr = "[email protected]";
MailAddress a = null;
try
{
a = new MailAddress(addr);
}
catch (System.FormatException ex)
{
Console.WriteLine(ex.Message);
}
if (a != null)
{
Console.WriteLine("OK: " + a.User + "@" + a.Host);
}
Console.ReadKey();

I am oblige to confirm that your code work in .net 4.5.1. I will try with .net 3.5...
from dkim-exchange.
I just tested
\"[email protected]\"\r\n\t<[email protected]>\r\n
Result: in .NET 4.5 it works, but 3.5 there's the exact same exception.
So this is related to 3.5 (Exchange 2007 & 2010)
from dkim-exchange.
Same result! This is a very interesting problem... :)
from dkim-exchange.
The problem for .NET 3.5 is the newline between the first (name) part and the second (address). If I replace it with space, also .NET 3.5 recognizes it correctly.
from dkim-exchange.
We should look the two MailAddress class difference between .net 3.5 and .net 4.5 to be sure to avoid any others problems...
Here the source code for 4.5.1 : http://referencesource.microsoft.com/#System/net/System/Net/mail/MailAddress.cs#b23cf10c5d2b82f1
from dkim-exchange.
QuickFix (for now): a1a145b
from dkim-exchange.
@networkthinking You can use version 1.8.3 now: https://github.com/Pro/dkim-exchange/releases/tag/v1.8.3
@AlexLaroche if you find the source code for 3.5 we can look for differences, but please create a new Issue for that. Thanks for your help!!
