[Mailman-Users] Any quantity restrictions in who email command?

[Ulf Dunkel]

Hi Mark.

I try to grab the members from various of my mailing lists via the email 
interface, but two of them with more than 1,000 users each won't let 
Mailman reply on my "who <password>" email to the relevant 
<mailinglist>-request at mydomain account.

Are there any quantity restrictions I have overseen (or forgotten)?

Thanks in advance for your reply,
