Description Tim Brooks 2001-05-17 20:32:42 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2smp i686)

Description of problem:
When trying to send e-mail to an smtp server running on 7.1 with tcp
wrappers enabled (i.e. /etc/hosts.deny --> ALL: ALL), the netscape client
will not send on the localhost.  The only way to get this to function was
to put in the line: sendmail : ALL in /etc/hosts.allow.  The following
lines did not work in /etc/hosts.allow:
ALL: localhost
sendmail: localhost

How reproducible:
Always

Steps to Reproduce:
1.Send an e-mail from netscape
2.
3.
	

Actual Results:  I received an error from Netscape:
The mail server responded
5.0.0 Access Denied

/var/log/maillog gave me the following error:

May 17 15:11:15 mailx sendmail[25415]: f4HKBF125415: tcpwrappers
(mailx.personalcarehmo.com, 127.0.0.1) rejection

Expected Results:  e-mail should have been sent

Additional info:

same problem here, except with fetchmail.

fetchmail -v reports "Access Denied" from the local
sendmail.

adding sendmail: ALL in /etc/hosts.allow worked for me too,
this is alright though, since DomainPortOptions in sendmail.cf
is locked to 127.0.0.1 anyway.

very strange.

Comment 2 Michael Schwendt 2001-06-15 19:10:35 UTC

What about this?

# /etc/hosts.allow
sendmail: LOCAL

Comment 3 Florian La Roche 2001-07-06 09:13:33 UTC

sendmail rpm should be fine.
