Better username-handling
« on: September 30, 2006, 03:14:21 PM »

I don't know if this is already in your svn-release or if you recieved this, but i sent it to your mailing list (without any result) ... However:

Yes, and in Addition: Make the table-headline of the mail-list "position:fixed". If you need a "clean" (as clean as possible... ;-) ) way to do this even for IE, please tell me, I'll make one.

However, here what I sent to the mailinglist:


I somehow "improved" the way how roundcubes handles virtual users... This is,
because my server panel (ispconfig) somehow creates an ugly virtual user table,
therefore i want strictly the real mail username as common-name for accounts, so
I moved the email2user BEFORE the first mysql-query

// PART OF / rcmail_login(...) //

  $imap_port = $CONFIG['default_port'];

 // try to resolve email address from virtuser table
  if (!empty($CONFIG['virtuser_file']) && strstr($user, '@'))
  $user = rcmail_email2user($user);

 // query if user already registered
 $sql_result = $DB->query("SELECT user_id, username, language, preferences
              FROM ".get_table_name('users')."
              WHERE mail_host=? AND (username=? OR alias=?)",


This way, the database is forced to be on a real-username basis and doesn't
create different addressbooks and settings by logging in with the different
aliases of the same mailbox (wich makes no sense at all...)

Another thing is, that I created faster mail2user and user2mail functions, use
them if you like, GPL Code as usual ;-), mention me in some
author/history/changelog if you like, I'm not one of these Super-EGO people who
need to be mentioned anywhere, but I'm not against it either ;-)

The functions are currently named "rcmail_getvlist", "rcmail_email2user" and

// SNIPPET for //

function rcmail_getvlist()
  global $CONFIG,$x_listcache;
      $t=str_replace("\t"," ",$t);
      while(strstr($t," "))$t=str_replace(" "," ",$t);
      list($x,$y)=explode(" ",$t);

function rcmail_email2user($email)

function rcmail_user2email($user)


Basically, the getvlist returns (cached run, for future usage in sessions
and/or multiple usage) a multi-dimensional array, value 0 contains an
assoc-list with mail2user and 1 a list of user2mail. so you easily get the
user: $user=$l[0][$email] ... the vlist basically works stable on all
sendmail-style mailtab files, space or tab seperated (postfix, sendmail, exim,
etc.) with single user to alias associations.

Yeah, one other thing: I strongly recommend that you don't rely on any
user2email functions, because often there are many aliases for the same user,
and there is no rule to tell wich is the prefered one...

Okay, hope I could help you, thanx for the only free webmailer I >want< to use
