Description of problem:
I've recently noticed that sendmail loses outgoing mail. The
/var/log/maillog shows the from= being logged, but not the to=
and the message never appears to be queued. Problem seems to
occur most often with remote mail, mail to other users in the
domain seems to work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Problem showed up after applying the latest set of updates to glibc and
util-linux, so may be related. RPM won't let me backout glibc-2.2.4 for
an older version though, because it's now got glibc-common, so it's hard
to verify that this is the cause.
Is everything working fine after a "service sendmail restart"? There is a
problem with syslog logging after logfile rotation. Could this be the
Florian La Roche
No, the problem is NOT logging related (I have confirmed this with tcpdump). It
also persists on a clean install of RedHat7.2 + updates.
More investigation shows that the bug only occurs with nmh, and I can workaround
the bug by adding "send: -verbose" to $HOME/.mh_profile. It does not occur in
Red Hat 6.0 + updates, so I suspect changes in nmh between 6.0 and 7.x.
So this is a problem with nmh and not sendmail?
It's clear that nmh does something different in the way it submits mail when
verbose logging is enabled. I don't know if the problem is a bug in nmh, or
a bug in sendmail that is triggered by the difference in submission. My guess
is that nmh is incorrectly configured.
So, its ok to close this bug?
Does it still happend on RH7.3 or 8.0?
The bug is still present on 7.0 + updates; and closing bug reports because
they haven't been solved in over a year is not acceptable. I haven't tried
I sugest closing it because it is a nmh bug and not a sendmail bug.
I think sendmai is so much mature to have a bug that says:
"sendmail is loosing mails".
One option is to close this bug and open a new one for nmh.
Has that been confirmed?
For me yes, because Sendmail never lost any mail in my mailserver.
Maybe you can post a test-case for nmh and sendmail so other can reproduce it.
Again, I don't believe Sendmail has any bugs because it is working for me.
The test case is simple: send mail using nmh, without the verbose option.
The difficulty is deciding which is incorrectly configured. I don't believe
either has a bug, since other unixes running the same versions don't show
this behaviour. However, I believe one is setup wrongly. I don't believe
we've shown which is it yet.
can you post your sendmail.mc file and nmh configuration?
Have you tryied using the standard sendmail and nmh config files?
I'm using the default nmh configuration files (the only addition is "send:
-verbose" in $HOME/.mh_profile, which is my workaround for the problem).
The sendmail.mc is that shipped with RedHat7, plus the addition of:
