[Mailman-Users] digest users problem

[neverness in the neverland]

Hi,

I have problem with sendmail hanging only when mailman sends
email to digest users:
root     16543  0.0  0.5   584   604 ??  I      4:12AM    0:00.01

It seems that mailman never sends the whole message. Any ideas ?

Openbsd 2.6, sendmail 8.9.3, mailman-2.0beta2. 

Everything else seems to be working fine.

thanks
