Description worthaboutapig 2016-01-22 06:08:45 UTC
The attribute 'deliveryFormat' is not serialized from 'system.net/mailsettings/smtp' which causes an exception at runtime:

Error deserializing configuration section smtp: Unrecognized attribute 'deliveryFormat'.
  at System.Configuration.ConfigurationSection.DeserializeSection (System.Xml.XmlReader reader)

To reproduce, create a new instance of the SmtpClient (var mailClient = new System.Net.Mail.SmtpClient(...)) and have the relevant configuration setup in the web.config/app.config.

Workaround: Remove the attribute from the .config XML, though what format it's in, I don't know.

The property is missing from https://github.com/mono/mono/blob/master/mcs/class/System/System.Net.Configuration/SmtpSection.cs, but is defined at https://msdn.microsoft.com/en-us/library/ms164240(v=vs.110).aspx

I can't find any information about this at all, as to whether there's some reason it's left off, but it's certainly a bug.

Tested on 4.2.2 on ArchLinux, packaged Mono

Ok, thanks,but presumably this value is still ignored by the default System.Net.Mail SmtpClient?  Shouldn't this be functionally equivalent to the MS version?
