Squirrelmail server issue

[rboon]

Ok. Being new to the linux world, I am proud to say that I have managed to get Fedora Core 6 and a squirrelmail server running. Well, its running and I can send mail from the web interface anyway. Now this is where I am really really confused. If i use a mail client ...say Outlook from any machine anywhere, I constantly get Relay access denied. I have googled this for the last week and a half and am getting more confused. I know it has something to do with postfix and trusted relay, but i for the life of me can't figure out what. Can anyone help me out please?

ok. mental note

Specify "mynetworks_style = class" when Postfix should "trust" SMTP
# clients in the same IP class A/B/C networks as the local machine.
# Don't do this with a dialup site - it would cause Postfix to "trust"
# your entire provider's network. Instead, specify an explicit
# mynetworks list by hand, as described below.
#
# Specify "mynetworks_style = host" when Postfix should "trust"
# only the local machine.
#
mynetworks_style = class
mynetworks_style = subnet
#mynetworks_style = host

please note the red. Problem fixed. Seems that all 3 of these lines were uncommented causing the exact problem described above it

Anyone know how to adjust mail attachment size in SM?

thanks for all the help.

Ok. Really need help here bad. I can't get remote users to have the ability to send mail. This has become a problem. SquirrelMail, FC6, appache, dovecot, and postfix are all working for those on the company domain, but anyone at their homes or in the field can't send mail. They are getting Relay accesss Denied. I have everything setup so that I thought it would allow local account users to relay mail no matter where they are, but it isn't working. HELP!!!
