The first line below, starting with 127.: will be used by any webmail
operations on the server.
Currently, the next line, starting with only a :, will be used by all
other processes.
If you want to speed up submission of emails for local clients, you
could add a line starting (for example) with 192.128.0.:, otherwise
identical to the 127: line, which would allow local clients to send
email without any concern to Chkuser for the number of connections at
one time, etc. (You would want to add the DKSIGN segment there, so
that all outgoing mail gets signed.)
But that's making some assumptions about your network topography that
I'm not sure are correct. In short, the addresses in tcp.smtp are all
about the addresses of other machines connecting to your QMT, not the
address of your QMT.

hmmm i don't know what is happening. The slow response when sending

Can we please try to continue on getting the culprit?
Could it be my tcp.smtp?
127.:allow,RELAYCLIENT="",DKSIGN="/var/qmail/control/domainkeys/%/
private",RBLSMTPD="",NOP0FCHECK="1",QMAILQUEUE="/var/qmail/bin/

:allow,BADMIMETYPE="",BADLOADERTYPE="M",CHKUSER_RCPTLIMIT="50",CHKUSER
_WRONGRCPTLIMIT="10",QMAILQUEUE="/var/qmail/bin/simscan",DKSIGN="/
var/qmail/control/domainkeys/%/private",NOP0FCHECK="1"
Do I really need to add my local address 192.168.0..5 of the server
here? Though this is added I'm still connecting using the IP
address from the outside connection that
uses :allow,BADMIMETYPE="",BADLOADERTYPE="M etc.
Thank you again.

http://wiki.qmailtoaster.com/index.php/Certificate There's a
little bit about self signed certs at the end of the page. If you
need more than that, there are many web pages about creating a
self signed cert. Any one should do. The certificate is the same
as would be used by apache. Google is your friend. ;) Tom

Yes it seem to be responding well now after I did a qmailctl
cdb without actually changing anything. But I still have this
prompt and smtp slow to respond sometimes but atleast not as
slow as before. Could it be that there are several who are
trying to connect? How will I be able to check on how many
active connections I have for smtp and pop3?
You'll need to configure Outlook to not use SSL, or purchase a
cert accredited by Outlook.
I'm not so sure about that Jake. ;) I've set up Outlook'03 (and
'07 I believe) to use SSL with SMTP on the submission (587)
port. I presume it's actually doing TLS. The certificate isn't
the default localhost cert, but it is essentially a self-signed
cert (signed by CA-Cert.org). IIRC I did have to manually add
the CA cert chain to each machine though, which might not be
practical for some folks. So a self-signed cert can be used with
Outlook. A purchased cert is much easier to set up though,
especially on anything but a small scale.
