Hello all, im appologize ahead of time but i am new to linux. i am currently switching from M$ sbs03 to ubuntu 10.04 with ISPConfig 3. i cannot send or recive mail through squirrelmail. i use dyndns for Mailhop outbound and inbound also for dynamic dns services. to cut it short i belive the problem may be with the postfix master.cf or main.cf although i cannot be sure the ip is updating correctly. i would be happy to show any configs and any and all help is appreciated.
