Problem Installing Postfix in 6.1

[Alex Alborzfard]

I'm having trouble installing Postfix. After selecting the options (TSL,
Mysql), after displaying output that it can't fetch
postfix-2.2.9-tar.gzfrom various sites,
it displays this message:
"Couldn't fetch it - please try retrieving this port manually into
/usr/ports/distfiles/postfix and try again.
**** Error code 1

I've tried google and the FAQ, but haven't found anything. When responding,
please keep in mind that I'm a newbie.

Thanks

Alex
