CentOS - Jul 2007 - slow SMTP-AUTH

Hi,

	I installed sendmail on a centos-4 openvz VM.  I set up SMTP-AUTH and 
when I try to send mail using this server, there is a big delay in which 
my e-mail client (Mozilla Thunderbird) just hangs.  The server, on the 
other hand, is idle at the same time.  It does that no matter if I use 
no encryption, TLS, or SSL.  When the client is 'hung' sendmail, on the 
server side haven't logged anything yet for this connection.

Any idea?

Regards,

Ugo

Since nothing is logged on the server, it sounds like there is a firewall (or
other networking problem) in the way. You should use WireShark (or tcpdump) on
the client to capture the network traffic.
