Hi Fernando, >From Section 5.3 of the docs located at http://www.squirrelmail.org/docs/admin/admin-5.html: "Using different username for SMTP relaying If SMTP server uses different username and password for authentication, since 1.5.1 version SquirrelMail can use one username and password for entire SquirrelMail installation. They can be set in config/config_local.php $smtp_sitewide_user and $smtp_sitewide_pass configuration variables. If you use older SquirrelMail version and want to use single user/password for SMTP authentication, you might have to install local SMTP server and set it as smart relay. See SMTP server's documentation about email relaying through other SMTP server." Hope this helps. -----Original Message----- From: squirrelmail-users-bounces@xxxxxxxxxxxxxxxxxxxxx [mailto:squirrelmail-users-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Fernando M. M.

Could someone help me with this problem? What should i check? Thanks, Fernando. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
