<p style='margin-top:0;margin-bottom:10px;'>which is perfect.<br/>
Also ch.qos.logback.classic.ViewStatusMessagesServlet shows my emails with 10 rows saying</p>
<p style='margin-top:0;margin-bottom:10px;'>INFO | SMTPAppender | About to send out SMTP message "ERROR myLogger myMessageNNN" to <span class="error">[xxx@xxx.yyy.com]</span></p>
<p style='margin-top:0;margin-bottom:10px;'>with N in 0 to 9, but the order of emails is shuffled to 7-0-9-2-8-1-4-3-5-6, which is still ok.</p>
<p style='margin-top:0;margin-bottom:10px;'>But unfortunatly, in my email account I find 10 equal emails, all with subject "ERROR myLogger myMessage8" and body</p>
<p style='margin-top:0;margin-bottom:10px;'>-----------------<br/>
ERROR myLogger</p>
<p style='margin-top:0;margin-bottom:10px;'>myMessage6<br/>
-----------------</p>
<p style='margin-top:0;margin-bottom:10px;'>So instead of sending 10 emails, one of them is sent 10 times. Even worse, subject and body of that email do not correspond to each other.</p>
<p style='margin-top:0;margin-bottom:10px;'>All 10 emails do have exactly the same Message-ID.</p>
<p style='margin-top:0;margin-bottom:10px;'>I tried this with logback 1.1.2, 1.1.1, and 1.1.0 (fetched from mvnrepository) and it always shows the same behaviour.</p>
<p style='margin-top:0;margin-bottom:10px;'>I tried it with two different smtp servers of my employer, and I did access both via Thunderbird and SquirrelMail, but this makes no difference.</p>
<p style='margin-top:0;margin-bottom:10px;'>If I do a "Thread.sleep(1000)" before each log.error, everything works as expected.</p>
