Summary:	KMail default Message-ID makes email appear as spam to some filters

Description support.intranet 2010-05-28 14:46:55 UTC

Version:           1.13.3 (using KDE 4.4.3) 
OS:                Linux

With my payed hostname if I send an email from KMail providers like gmail consider it as spam. A workaround is to add a custom suffix to Message-ID in the Settings. With Thunderbird or Squirrelmail (same machine, same domain) everything is fine.
Reported from forum discussion here (http://forum.kde.org/viewtopic.php?f=20&t=88042)

Reproducible: Always

Steps to Reproduce:
1) Get a payed email domain
2) Configure KMail to use it
3) Send an email

Actual Results:  
Most providers will simply ignore the email or mark it a spam

Expected Results:  
The email should be correctly received

Thank you for taking the time to file a bug report.

KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
