Hi I'm getting such error while tryying to send e-mail everything worked fine till I changed my outgoing mail host from falcon.myfakedomain.pl to poczta.myfakedomain.pl but I don't know why the squirrelmail still gets the old one. Message not sent. Server replied: Requested mail action not taken: mailbox unavailable 450 4.1.8 <biuro@xxxxxxxxxxxxxxxxxxxxxx>: Sender address rejected: Domain not found in config check all is ok Base URL detected as: http://localhost/poczta/src (location base autodetected) Checking outgoing mail service.... SMTP server OK (220 ESMTP on poczta.myfakedomain.pl !) config tool shows this A. Update IMAP Settings : localhost:143 (dovecot) B. Update SMTP Settings : localhost:25 I also changed those settings from localhost to poczta.myfakedomain.pl but got no effect /etc/hosts looks like this 127.0.0.1 localhost *.*.*.118 ns1.myfakedomain.pl falcon *.*.*.119 poczta.myfakedomain.pl hostname is falcon I tried to remove and install again squirrelmail but got no effect on this one got no idea from where squirrelmail grabs the old falcon instead of poczta. Sending e-mail by outlookexpress and other clients works fine only squirrelmail does not work. Any idea what to do ? ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
