ML discards some messages?

[Alexander V. Chernikov]

Hello list!

What is appropriate mail address to send messages to?

 From previous postings I see (sorted by popularity DESC):

* bird-users at network.cz
* bird-users at trubka.network.cz
* bird-users at atrey.karlin.mff.cuni.cz
* bird-users at bird.network.cz

I send messages mostly to @network.cz domain and _sometimes_ they are 
silently discarded somewhere:

X=TLSv1:DHE-RSA-AES256-SHA:256
2012-04-02 00:46:09 1SERey-000O5t-0U Completed

Unfortunately, remote SMTP answer was not logged but I suppose 
'Completed' without any previous error means that '250 OK' has been 
received.

However, I can't see this message neither in my 2 different mailboxes 
nor in "unofficial ML archive" at http://marc.info/?l=bird-users

Am I missing something?
