The mailing list for listmasters using Sympa

["Valics Lehel" <address@concealed>]

Hi all,

I have the following scenario.
A list with 3000 subscriber (newsletter setting)

sympa.conf
## Maximum number of recipients per call to Sendmail
nrcpt           25

## Average number of recipients (ie max. number of different domains)
## per call to Sendmail
avg             10

## Max. number of Sendmail processes (launched by Sympa) running
simultaneously
## Proposed value is quite low, you can rise it up to 100, 200 or even 300
## with powerfull systems.
maxsmtp         20

When I send a mail to this list I get a huge "mailq" and seems that the
messages is not delivered in an hour.
Also I get

ps -ax|grep sendmail
15827 ?        S      0:25 sendmail: rejecting connections on daemon MTA:

Why's that? What I'm doing wrong?

Regrads,
Valics Lehel
