Problem subscribing this usergroop

["Holger Matschinski" <homa@homa.de>]

Hello there!

By the way, can someone tell me what's the reason that I can't subscribe
this usergroop? I got the Mail from Majordomo to authenticate my
subscription by sending

auth _my-number_ subscribe minivend-users homa@homa.de.

in the body of a mail back to Majordomo. I did so, several times, but my
Outlook Express everytimes gives the answer (translated by myself from
German)

The message could not been sent, because one of the targets was not accepted
by the server. The not accepted e-mail-adress is 'Majordomo@minivend.com":'.
Concerning '', Konto: 'homa@homa.de', Server: 'homa.de', protokoll: SMTP,
serveranswer: '553 <Majordomo@minivend.com":>... unbalanced '"'',
Connection: 25, secure(SSL): no, servererror: 553, error-number: 0x800CCC79

I' ve tryed to send it in two lines separatet with a backslash, even with no
success.

Anyone with an idea?

Thanks,

Holger
