sendmail STARTTLS problem?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi:

I'm having some difficulty configuring my sendmail to use STARTTLS 
with my Winblows Pegasus Mail client.  I uninstalled and reinstalled 
sendmail with yum so I would have a clean installation.  I modified 
the sendmail.mc file, uncommenting the define(`confCACERT_PATH,
define(`confCACERT, define(`confSERVER_CERT and 
define(`confSERVER_KEY lines.  The sendmail.pem file exists in 
/usr/share/ssl/certs, I did not modify it.  I enabled STARTTLS 
connections on port 465.  The rest of the file is unmodified.  The 
maillog shows no errors when restarting sendmail.  When I connect 
with my mail client however, no data is transferred and the socket 
eventually times out.  The following two lines then appear in 
maillog.

May  4 10:20:39 ljr-2 sendmail[11161]: STARTTLS=server, error: accept 
failed=0, SSL_error=5, timedout=0, errno=0

May  4 10:20:39 ljr-2 sendmail[11161]: j44HJngP011161: 
sagebrush.frazmtn.com [208.1.40.46] did not issue MAIL/EXPN/VRFY/ETRN 
during connection to TLSMTA

I'm curious if anybody uses Pegasus Mail with STARTTLS to connect to 
their Linux/sendmail boxes successfully and whether anybody 
recognizes what is causing the above errors.

Thanks very much for your help.
