Hi,
We're using some special UTF-8 characters in our mail subjects.
We found an interesting behaviour in character encoding when using Mailbee SMTP when it comes to mail subjects.
Some special UTF characters (but not all) work ok only when the subject is short. If it becomes longer, some of them turn into two question marks on the client. Of course, displaying UTF is client dependant, but we eliminated client program's fault (MS outlook in this case).
I'm not sure if i can copy + paste the subject here, but I'll try.
What we did was: we sent a few messages using mailbee and by outlook.
Not sure if this is relevant, but mailbee was working in direct sending mode (looking up MX servers on its own. We did not try with a relay server, but I assume its irrelevant).
Sending "topic ☀☁☂🎅🍴" as a subject works fine. (in case your browser can't display it, those are utf characters representing sun, clouds, umbrella, santa clause's face and fork/knive).
Sending "topic ☀☁☂🎅🍴 test asdasd as dasd asd asd as dsad asd asda sd adsad asdggfgf fd fgfd" makes only the first three UTF special characters appear correctly. Last two ones change into unreadable question marks.
Then we have resend the same subjects from outlook, and received it in outlook, the characters appeared fine. This leads me to believe there might be some bug with character encoding in mailbee that depends somehow on the size of the subject and it affects only some of the signs. That, or there is some flag i don't know about and didn't change it.
Thanks.

Please make sure you're using the latest build of the DLL, it's available for download at:
http://www.afterlogic.com/updates/mailbee_net_2.zip (for .NET Framework 2.0 or above)
http://www.afterlogic.com/updates/mailbee_net_4.zip (for .NET Framework 4.0 or above)
If the issue persists with the latest DLL build, please provide us with a simple self-contained sample which would allow us to reproduce the problem. Please use HelpDesk for sending it. Thanks!

Please download the updated build from the same location. It turned out the issue was related to surrogate characters (composite Unicode characters). It's now fixed.
Regards,
Alex
