hi,

yea - as mentioned in the bug report I can connect this way when I'm using the centos kernel, and I'm getting the 220 SMTP response. When I'm using the openvz kernel, the tcp connection gets established (I used tcpdump in parallel, an the the SYN, SYN/ACK, ACK sequence), but the 220 response is simply missing...

I discovered this problem only with one SMTP server I try to send emails to yet - according to some messages found in google groups it seems that the receiving SMTP server is an cisco pix or something like that.

iptables is disabled.
