Hi Jim,
A client of mine had an issue where it was the ISP that was causing
the "220*******************************" banner...something you might
consider.

This is known to happen with Cisco Pix firewalls. The fixup smtp code
they implement is buggy at times. MTA's such as postfix have a specific
workaround for Pix firewalls that works on the fly.

I am adding this incase it might help someone else
the iss: my smtp banner was showing being masked by mxtoolkit
like so 220 ************************************
even though I had a good one
and a good me
all under /var/qmail/control/ me & smtpbanner
here was the solution
I have a cisco pix 515e firewall
and that conf in the pix
fixup protocol smtp 25
so i do a
fixup protocol smtp 25
and a write mem
and -- now good
it was the firewall ... that is what i currently think.

Hi,
I have just run a test against one of my servers.
1. dmarc, well I do not have one either. Not sure if I need to either.
Does anyone else have one?
2. check what the "host" command for your ip returns against the
"me" file
in /var/qmail/control/me
Might pay to edit the "me" file and put in mailhost.theppsgroup.com
instead of what might be there.
3. If you have not enabled TLS for mail then that is up to you.
4. SPF is not difficult really
example at the cli type
#dig TXT theppsgroup.com
This will return your current TXT records from the DNS.
If you have no TXT data then edit your DNS record and add an entry
like this.
"v=spf1 a mx ip4:168.215.62.222 -all"
If you have more than one mail server that send email on your behalf
of your domain
then add a second entry in this line
http://www.openspf.org/SPF_Record_Syntax

Friends,
If I check my server with
http://mxtoolbox.com
I get the following complaints
Category Host Result
dmarc theppsgroup.com Missing or Invalid Record
smtp mailhost.theppsgroup.com Reverse DNS does not match
SMTP Banner
smtp mailhost.theppsgroup.com Warning - Does not support TLS.
it is true I have no dmarc ( i was thinking it is not required ...)
and I have tried to do the spf and the banner thing
i have tried googling and sorting it out -- thus far I am unsuccessful
I wonder if someone could give me some wisdom on how to resolve these
thanks
