strange mail delivery (only 1 at a time)

dear all,

I hope not to pose a FAQ.

I use postfix with SpamAssassin (via procmail). Now, I found out that,
though there are about 15 messages in the queue, postfix seems to
deliver them one by one or rather directory by directory (inb
/var/lib/postfix/active).

postqueue -f does not help, sendmail -q neither.

Any hints?

Thanx in advance,

thorsten

That's easy to fix, but I can't be bothered.
