Greetings. Package mix: Sendmail, Dovecot, POP-before-SMTP and Squirrelmail. I´ve configured Sendmail to require SASL auth as per http://www.joreybump.com/code/howto/smtpauth.html Sending, receiving & IMAP works great on most workstations (esp Linux :-), except for workstations running Outlook 2003. Outlook_2k3 receives OK (POP3), but fails on send (SMTP): ¨Relaying denied... auth required¨. We´ve got ´server requires auth´ in Outlook_2k3 checkbox checked, but since I don´t have this email client installed on any of my workstations in front of me to test it, I can´t see what I´m overlooking. Has anyone any insight into this? TiA Blessings, Stu@
