Basically, I installed a new server 2 weeks ago, and just pointed dns
for one domain to it the other day. Just my luck, I can't send email
from the server (using "mail" from the command line), nor can I send
email from email clients (Thunderbird and Outlook). However,
squirrelmail works fine. This is a web hosting server.

The cf is the same as the cf on my old server, and I can't seem to
figure out what to try next. I've restarted SASLAUTHD (which always
fixed the problem on my old server).

The logs report the following:
Apr 27 23:22:40 bigdog sendmail[20811]: l3S3McJV020811:
c-76-108-129-79.hsd1.fl.comcast.net [76.108.129.79] did not issue MAIL/
EXPN/VRFY/ETRN during connection to MTA

When I telnet, this is what I get:
>telnet mail.engineno9inc.com 25
Trying 209.62.15.67...
Connected to mail.engineno9inc.com.
Escape character is '^]'.

As I mentioned, this worked (and still works) on my old server and the
cf's are the same. The difference, however, is that the new server
uses sendmail 8.13.1, and the old uses 8.12.10, and I'm on different
OS's (CentOS 4.4 is the new one, FC2 on the old one).

I would appreciate any tips or nudges in the direction of a solution.

Thanks,
Alden

Dont copy cf files from host to host.

Copy only modifications made to sendmail.mc that you reasonably
believe you will require on the new box. sendmail.cf should always
only be generated from sendmail.mc

The only way it would have fixed anything would be to allow
successfull authentication for sendmail to permit relay.

Well I suppose its possible your mail client is requiring STARTTLS
support, which isnt being offered.

Odds are there is a much longer list of differences. And again, dont
copy cf files.

The error message is below. To quote:

Sorry for the miscommunication; I didn't copy the cf file. I meant
that they were both "stock" installs, and are the same. I wouldn't
change cf files. I know to make changes in mc.

Yes. These both host multiple domains. On my old server, when I got
the .
...did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
error, I restarted SASLAUTHD.

Why would that be? Should I check sendmail.mc (or somewhere else) for
something in particular?

Of course, there are lots of differences. I *thought* these are the
most relevant to highlight at this point. If you want to know about
anything else, please ask. I didn't want to include a laundry list of
differences.

I run MailScanner/SpamAssassin/ClamAV on both machines. The versions
of all three programs are newer on the new box. I probably should
have mentioned this in the first email.

Also, Ensim Pro X is installed, but my host's autoprovisioning system
didn't load it properly the first time, so they had to reload it.

Thanks,
Alden

This isnt the error from the client end and is this the only log
entry?

If this is occuring over the network, do you think perhaps you can
perform a network capture with tcpdump and/or wireshark?

can you post the output

grep -v '^dnl' < /etc/mail/sendmail.mc

on both old and new?

Or allow authentication to occur, if the client is attempting it.
