I have noticed there is a restriction of subject header of a email within 33 symbols when the email is sent from a forum by means of DotNetOpenMail. If more symbols are added a abracadabra turns out.  Could you please tell me, are there ways to increase this value?

Hi Joe!

Thank you for your reply :)

 I get this problem when I set non-ASCII encodings like utf-8 or koi8-r here:

 <add key="SmtpPreferredEncoding" value="utf-8" />

 

I have set a value directly: 

mail.Subject = "mojoPortallllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll"; 

and I have experimented options here: 

if (smtpSettings.PreferredEncoding.Length > 0)
  {
  mail.HeaderEncoding = DotNetOpenMail.Encoding.EncodingType.Base64;
  mail.HeaderCharSet = Encoding.GetEncoding(smtpSettings.PreferredEncoding);
  }
but these actions have not helped. :(

I think, that DotNetOpenMail defectively supports non-ASCII encodings. 

 

 You are right, it is not a problem with DotNetOpenMail. I have set both values in the Email.cs directly: 

 mail.Subject = "mojoportalmojoportalmojoportalmojoportalmojoportalmojo";

 mail.TextPart = new TextAttachment("mojoportal");

and I have received the correct email.

 The problem arises when these values are taken from the en-US-ForumNotificationEmailSubject.config and en-US-ForumNotificationEmail.config files. Depending on a combination of Latin and Cyrillic characters in а subject header and a body of a email, a admissible quantity of characters in the subject header (which does not turn to abracadabra) varies. For example, if to write only Latin characters in both the subject header and the body, the admissible quantity of characters will be equal 53.

In case of the above-stated values in the above-stated files and such  setting: 

<add key="SmtpPreferredEncoding" value="koi8-r" /> 

I receive such email:

My settings in the Web.config file:

<add key="SmtpPreferredEncoding" value="koi8-r" /> 

 

I use Linux (Debian etch4), mono from svn and mojoPortal from svn too. But Windows users which is not using mono complained of the same problem to me. 

 

 

 All the same it is a problem with DotNetOpenMail.

When I have directly set the subject header of the email in length of 54 Latin characters in the Email.cs instead the 53, I have again received the garbled email.

Then I have written the following simple desktop application which does not have any relation to mojoportal: 

static void Main(string[] args)
  {
  System.Text.Encoding encoding = System.Text.Encoding.GetEncoding("utf-8");
  EmailMessage emailmessage = new EmailMessage();
  EmailAddress japanesefromaddress = new EmailAddress("xxxxxxx@xx.ru", "Svetlana", EncodingType.Base64, encoding);
  EmailAddress japanesetoaddress = new EmailAddress("xxxxxxxxxx@xx.ru", "Budunduk", EncodingType.Base64, encoding);

  emailmessage.HeaderEncoding = DotNetOpenMail.Encoding.EncodingType.Base64;
  emailmessage.HeaderCharSet = System.Text.Encoding.GetEncoding("utf-8");

  emailmessage.FromAddress = japanesefromaddress;
  emailmessage.AddToAddress(japanesetoaddress);
  emailmessage.Subject = "mojoportalmojoportalmojoportalmojoportalmojoportalmojop";

  emailmessage.TextPart = new TextAttachment("mojoportal");
  emailmessage.TextPart.CharSet = System.Text.Encoding.GetEncoding("utf-8");
  emailmessage.TextPart.Encoding = DotNetOpenMail.Encoding.EncodingType.Base64;

  SmtpServer smtpServer = new SmtpServer("smtp.yandex.ru", 25);
  smtpServer.SmtpAuthToken = new SmtpAuthToken("xxxxxxxxxxx", "xxxxxx"); 
  emailmessage.Send(smtpServer);
  }

and I have once again received the garbled email. 

I have found discussion of a similar problem here:

http://sourceforge.net/forum/forum.php? thread_id=1812211&forum_id=441285 

but there this problem still have not solved.
