Don't ask me why I even remembered this, but I did, which may help you. For some reason, the default postfix install on TSL 2.2 has a separate transport defined for Yahoo, Hotmail, and AOL destinations: [EMAIL PROTECTED] /etc/postfix$ grep bigandslow * master.cf:bigandslow unix - - n - - smtp master.cf.rpmnew:bigandslow unix - - n - - smtp transport:# when sending mail tol. "bigandslow" is defined in master.cf transport:aol.com bigandslow: transport:yahoo.com bigandslow: transport:hotmail.com bigandslow: I've never really paid attention to it (other than to notice it once before) as it all seems to work fine for me, but my guess is that these transport definitions may be bypassing your relay host definition and therefore the reason you can't send mail to Hotmail or Yahoo (and I suspect AOL would be the same). You may want to investigate these settings in postfix.
