My daughter gave me an older iBook running OS 10.4.11 and I can't seem to send emails using the Mail application I can receive email with no problem. I have changed the ports to recommended 995 or 465 with no results. The only way I can receive mail is if ports are set to 995. Every other aspect of this iBook works fine. I just use this iBook on trips and not for heavy use so this is not critical but it would be convenient to be able to send mail. I have tried everything including duplicating the accounts as they are set up in my iMac. Any ideas?
