[Pkg-exim4-users] flawed configuration causes mail server errors

[Haines Brown]

I've been fiddling with exim4 and sa-exim, under Debian etch, and
believe I've retreated to my original (monolithic)
configuration. However, an artifact of that experiment are periodic
error messages coming back from my ISP's mail server. For perhaps one
out of three fetchmail reports I get, for example: 

  fetchmail: Server CommonName mismatch: localhost 
  	     != pop.hartford-hwp.com 
  fetchmail: Server certificate verification error: self signed
  	     certificate 
  2 messages for brownh at hartford-hwp.com at pop.hartford-hwp.com
    	     (109887 octets). 
  reading message
  brownh at hartford-hwp.com@mymail.myregisteredsite.com:1 of 2	
  	     (89896 octets)................... flushed
  reading message
  brownh at hartford-hwp.com@mymail.myregisteredsite.com:2 of 2	
  	     (19991 octets)................... flushed 
 
As this fetchmail message indicates, the two mail messages were
actually downloaded successfully despite the verification problem.

It seems that the error message says that it does not find that
pop.hartford-hwp.com is an alias for localhost. My local hostname is
"teufel". My /etc/hosts file has:

  127.0.0.1	localhost.localdomain localhost
  192.168.1.1     teufel.hartford-hwp.com teufel
  ... 

I'm not running SSL, but I believe my ISP may be using it. Other than
a possible connection with SSL, I've no idea what the fetchmail
message means.

In /etc/exim4/email-addresses I put:

   user: brownh at hartford-hwp.com

In /etc/exim4/passwd.client I have (I obfuscated the PW here):

  *:brownh at hartford-hwp.com:NNNN

In /etc/exim4/updat-exim4.conf.conf I have (registeredsite is my ISP): 

  dc_eximconfig_configtype='smarthost'
  dc_other_hostnames='hartford-hwp.com'
  dc_local_interfaces=''
  dc_readhost='hartford-hwp.com'
  dc_smarthost='mymail.myregisteredsite.com'
