Topic: Maillog Error: maildrop[4756]: Cannot determine my username.

[Zen]

Hi, after the recent update of my sme 8.1, it stopped receive any email. They are all in qmail queue and in qmail log i've this error:

Code: [Select]

delivery 145: deferral: /usr/bin/maildrop:_Cannot_determine_my_username./
This for all the users and groups. Is there a solution?

Thanks in advance,
Bye

[Zen]

Maildrop is not a part of the core, but...in which contrib have I installed it? User-panel? Vacation?
If I remove this contrib, can i solve the problem?

[Zen]

Update...
in

Code: [Select]

/home/e-smith/files/users/user01 I found some files

Code: [Select]

.mailfilter
.procmailrc
.qmail
.qmail-default
.qmail-junkmail
.vacation.msg
.mailfilter.log
.mailfilter.log.1
.mailfilter.log.2
Now, moving all this files, I started to receive again but i've lost all the qmail queue. How can i retrieve all those messages?
What is strange is that those files were not recreated as I expected.

Edit:
The files have been recreated after a qmHandle -a command.

The strange is, until the file .qmail is in the folder, i can't receive anything; only when the file .qmail is deleted or moved and after a qmHandle -a I start to receive my emails. Everytime i must repeat this procedure or i give that error.

.qmail file is necessary for qmail to work
You are watching in the wrong direction..

[Zen]

Any suggestion on where to watch?

My steps (as you can see on this log):

I don't know where can I watch to solve this problem

[Stefano]

First of all remove maildrop or, if possible, disable it

Then, start studying SME's template concepts (here and in the developers' manual)

[Zen]

Did it, but without success.

[Stefano]

Please describe exactly what you did and how

Sep 25 14:44:30 Installed: kernel-2.6.18-371.12.1.el5.i686Then i tried to remove maildrop, always from webpanel, pressing the button "Remove additional software".
After this i tried to re-install mailsorting, cause i thought that it would have installed maildrop, but it did not.
So i open a console session and i wrote:

Code: [Select]

yum install maildrop --enablerepo=smecontribs(after every single operation i gave the

Code: [Select]

signal-event post-upgrade; signal-event restart)
After this i tried to reinstall also userpanel (cause i think that one of these operation could "reset" my server to a functionally state).
The last passage was

Code: [Select]

yum --enablerepo=smecontribs install smeserver-userpanel.
After i used MC and tried to remove my .qmail file and the other files in my folder (because some time ago i solved in this way another problem)...and seems it works, for a little, until .qmail isn't recreated.

[Zen]

Ah, i have also verify the file and folders permissions and seem all ok.

This is my .qmail file:

i verified my other (not updated) server, and my qmail file is different.

removed this line

Code: [Select]

| /usr/bin/maildrop ; if [ $? -ne 0 ] ; then exit -1; else exit 99; fi;again seem it works...

(i know isn't the right way to precede, because is "a tentoni" but...now my priority is to solve this problem )

You may have a custom template fragment doing bad things.  Try this:

# ls -alhF /etc/e-smith/templates-user-custom/.qmail

If anything is in there, what are the contents of those files?

I'm not sure I agree about maildrop not being part of the standard distro--the RPM is part of the ISO.  Don't know if it's installed by default, though it is installed in my SME 8.1 VM, and I don't recall customizing it at all.

[Zen]

Code: [Select]

[root@server ~]# ls -alhF /etc/e-smith/templates-user-custom/.qmail     
ls: /etc/e-smith/templates-user-custom/.qmail: No such file or directory
[root@server ~]#


[DanB35]

OK, how about this:

# grep maildrop /etc/e-smith/templates-user/.qmail/*

[Zen]

Code: [Select]

[root@server users]# grep maildrop /etc/e-smith/templates-user/.qmail/*
/etc/e-smith/templates-user/.qmail/50Filter:      return '| /usr/bin/maildrop ; if [ $? -ne 0 ] ; then exit -1; else exit 99; fi;'
/etc/e-smith/templates-user/.qmail/50Filter:        if ($qmail{FilterType} eq 'maildrop' );
/etc/e-smith/templates-user/.qmail/76Filter:      return '| /usr/bin/maildrop ; if [ $? -ne 0 ] ; then exit -1; else exit 99; fi;'
/etc/e-smith/templates-user/.qmail/76Filter:        if ($qmail{FilterType} eq 'maildrop' );
[root@server users]#

uhm...that line

Code: [Select]

| /usr/bin/maildrop ; if [ $? -ne 0 ] ; then exit -1; else exit 99; fi; is the same that is in "/home/e-smith/files/users/alberto/.qmail" that i don't have in my other clean server.
