sendmail 8.13.6 on FC2 server with SASL/STARTTLS

[Anne H]

Hi,

We installed sendmail 8.13.6, but authorization using a username and
password from Thunderbird is not working as before.

I don't have time to upgrade the server to FC4 or 5 right now. I'd just
like to configure sendmail 8.13.6 so that it worked as before.

The latest sendmail built for FC is 8.12.11, so I can't use that because
of the security problem.

The instructions with sendmail were used:
sh Build
sh Build -c -f `pwd`/devtools/Site/site.config.m4

to include STARTTLS, etc.

The previous configuration files (sendmail.mc) from 8.12.11 were
used.

The only thing I can think of is that the sendmail binary
produced is a dynamic library, whereas the one distributed
with FC2 is a shared executable. I've built sendmail shared, but it
fails with a segmentation fault.

Does anyone know the ENVDEFS that should be used to build
a shared binary for FC?

Thanks in advance. Any advice appreciated.

What's in the mail log when you try to send a mail?
What's the output of

telnet localhost 25

and then

ehlo localhost

?
What's the output of

netstat -tap

?

so STARTTLS is starting. Perhaps it has to do with AUTH not listing PLAIN
or LOGIN?

Not sure what you are looking for with netstat. It is really long so
I just cut out the part about imaps and pop3s.

If I build sendmail with
APPENDDEF(`confLDOPTS', `-shared')

I get a segmentation fault. It doesn't start at all.

Yes, some email clients such as Outlook Express need LOGIN.

I wanted to see if sendmail is running, but you didn't post that part (or sendmail is really not running).

Yes, sendmail is running.
