[courier-users] [authlib PATCH] - Extra vars in AUTH cmd
Hi Sam,
Here's a small patch which allow to transmit extra informations to the
authlib daemon.
TCPREMOTEIP and TCPLOCALIP (if they are defined) are appended at the end
of an AUTH cmd.
Useful to complete logging or give a way to allow/deny from IP a given
service.

[courier-users] Search for a good method to match From and To headers
Hi all,
I search for a nice regexp to match exactly an address collected in From
or To headers.
Here is the context :
My maildroprc file builds 2 lists from headers 'From:' and
'To:':
TO_LIST=
foreach /^(to|cc|resend-to|resent-cc):.*/
{
TO_LIST = $TO_LIST$MATCH
}
FROM_LIST=
foreach /^(From|X-Envelope-From|Envelope-Sender|Resent-Sender):.*/
{
FROM_LIST = $FROM_LIST$MATCH
}
Now
each variable is filled with a list of newline separated email addresses.
In my $HOME/.mailfilter I want to match exactly an address in one of
this 2 variables. My first try was to do like that :
if ( $FROM_LIST =~ /[EMAIL PROTECTED]/ )
{
}
but it doesn't works.
Where is my mistake ?
Thanks in advance.
Alain
PS : I don't want to use the hasaddr() function because it only works
with 'From:' headers.

[courier-users] How to store the result of a pattern score to a maildropvariable ?
Greetings, I want to store the result of a pattern score to a variable with the following filter rule : NBRECEIVED=/^Received:/:1 but maildrop(v1.5.3) returns me a syntax error. Bug ? What is the method to achieve this task ? Regards.
[courier-users] Advice and patch about 'cc' followed by 'to' in .mailfiler
Greetings All,
In maildropex man page I can read the following example :
if (/^From: [EMAIL PROTECTED]/ \
/^Subject:.*[:wbreak:]project
status[:wbreak:]/)
{
cc !john
to Mail/project
}
But in case of the 'to' temporary failure (Over quota for example)
john will receive several times the same message until the message is
successfully delivered or canceled which can be a problem.
I tried to simulate a better behaviour using an 'exception' command
similar to this :
if (/^From: [EMAIL PROTECTED]/)
{
OK=0
exception {
cc
$DEFAULT/.domain
OK=1
}
}
echo 'EXITCODE=$EXITCODE'
if ($OK == 1)
{
to
!john
}
else
{
exit
}
But in case of failure, the result is :
maildrop: maildir over quota.
EXITCODE=
and maildrop exits whith a null status. If I suppress the 'else' in
the above mailfilter script, the message is delivered in the $DEFAULT
maildir too (as expected ?).
By applying the following patch :

[courier-users] Two issues when deleting maildir folders
Hi All, Two issues were reported to me concerning folder deletion. My config : - Linux RH 8.0 - Maildirs are stored on NFS filesystem - Courier-Imap 1.7.3 - MUA : MS Outlook 2002 / MS Outlook Express 6 / Eudora 5.1.2 First case : I created this subfolder structure in my INBOX : + fold1 + fold2 - fold3 When trying to delete fold1, Outlook Eudora scan subfolders to delete deeper first and so on, while Outlook Express don't and try to delete fold1 first, which is accepted by the imap server leaving the two folders fold2, fold3 in the maildir with a parent folder unknown : . .. courierimapsubscribed courierimapuiddb cur .fold1.fold2 .fold1.fold2.fold3 maildirsize new tmp .Trash I know, Sam, you are not coding glue patches to correct M$ bugs (even if --enable-workarounds-for-imap-client-bugs has been developed :-) ) but I wonder if courier-imap server can refuse folder deletion in case of child folder existence. Second case : In very rare case we encounter a problem when deleting a non empty folder with MS Outlook / MS Outlook Express. Remember I use NFS filesharing. Here is an extract of a chat between MUA and imapd : ... -DONE -00X6 OK IDLE completed -00XF DELETE inbox.fold1 -00XF NO Cannot delete this folder. -00XG IDLE -entering idle mode ... After several attempts (its very difficult to obtain) we have discovered a temporary nfs file named .nfs0001d02e0144 in the cur subdirectory while folder deletion, preventing unlink success of this directory. At the end the folder was partially deleted (Maildir/.fold1/cur still exists) which cause an error when the MUA wants to refresh the folders list. We suspect concurrent imap channel opened by Outlook to send a LIST or similar command while deleting the folder leaving this temporary file which is released when we acknowledge the MS Outlook error dialog. Before installing version 1.7.3 of courier-imap (1.7.0 was our version for a long time) we never encountered this issue and I wonder if the new folder deletion behaviour which appeared in version 1.7.2 is not responsible of that. That's all folks. I'm impatient to have your feedbacks. Bye.
