too many unrecognized commands

hi folks,

big problem:
i'm using smtp proxy for reciving and relaying mails. everything worked fine for months but since today sending a mail from my windows smtp server outside takes about 3 minutes. no configuration changes where done and nothing was changed neither in smtp proxy nor in the mailserver (even no auto updates). after a look into the smtp log of asl i can see

2005:02:26-14:18:15 (none) exim[24493]: 2005-02-26 14:18:15 SMTP call from (mail.domain.xy) [192.168.x.x] dropped: too many unrecognized commands (last was "")

and after 3 minutes the mail is sent. but what's the problem? everything worked fine before and mails where sent immediately?!

Hmm, a tcpdump would have been interesting. With a tcpdump you could track the SMTP communication very detailed, if it's not encrypted.

tcpdump -i ethX -nn -s 0 -w /tmp/smtp.cap port 25
