Hi Gurus and everybody who is using qmail with VMAILMGR and Courier-IMAP!
After several tests we've found the problem and solved it!
No, it's not Outlook or anything else:
It's the authvmailmgr-module from vmailmgr.
So, if you want to log the user of a virtual domain who is using
courier-imap here's how to handle this:
The authentication-module of vmailmgr sends the "virtual name" of the domain
only! The solution:
Set an ENV with a name where no prog is using this ENV, except the
(modified) imapd from courier-imap:
look at "authvlib.cc" from the source of vmailmgr:
[...]
if(!lookup_baseuser(fulluser, basepw, virtname))
fail_login("Invalid or unknown base user or domain");
presetenv("VUSER=", virtname);
/*
the following line must be added! The ENV-Name can be different, but
notice to change this in the imapd.c too!
*/
presetenv("FULL_USER=", fulluser);
if(!virtname) {
if(virtual_only)
[...]
Notice: We add the ENV "FULL_USER" to the code so that the full
functionality of vmailmgr for qmail will be untouched!
Then make it with: make
and copy the program authvmailmgr to the auth-dir of courier-imap where your
original authvmailmgr resides.
Go to the source of courier-imap and look into the path imap for imapd.c.
Open the file and look for:
[...]
writes("* BYE Courier-IMAP server shutting down\r\n");
writes(tag);
writes(" OK LOGOUT completed\r\n");
writeflush();
emptytrash();
/*
Original: getenv("AUTHENTICATED")
NOW: getenv("FULL_USER")
*/
fprintf(stderr, "INFO: LOGOUT, USER=%s, ip=[%s],"
" headers=%lu, body=%lu\n",
getenv("FULL_USER"), getenv("TCPREMOTEIP"),
header_count, body_count);
exit(0);
}
if (strcmp(curtoken->tokenbuf, "LIST") == 0
[...]
Now we put the "FULL_USER"-ENV instead of "AUTHENTICATED"-ENV, because
according to vmailmgr the variable "fulluser" contains the domain and the
virtual user!
Next step:
STOP imap (& imap-ssl if your using)
make
make install (or copy the imapd to /usr/lib/courier-imap/bin or whereever
your imap-path is)
After you've overwritten the original imapd-prog: start it again and log
into your mailbox via imap and logout.
Look in the maillog (/var/log/maillog) and you should see something like:
INFO: LOGOUT, USER=domain.com-test, ip=[xxx.xxx.xxx.xxx], headers=0, body=0
Now you have the "alternative" Login from the user:
Login: [EMAIL PROTECTED] -> Becomes: domain.com-test
Login: domain.com-test -> Besomes: domain.com-test
I was surprised why NOBODY is interested to get the size of a virtual user
who is getting mails via imap over vmailmgr-auth!!!!
Any ideas?
