Gmail is giving my grandparents headaches in mail program

Question

So i talked my grandparents into ditching their old windows 2000 machine for a new macbook.
I signed them up for a gmail acct. and set everything up in Leopards mail program and everything was great for about 4 weeks. Now they are constantly getting error messages from Mail that the password is being rejected. Occasionally it will work and let an email or 2 through. This is mostly occurs on sending but occasionally on recieving as well. Is gmail and osx mail just a bad combo or what? is there a better free email acct option out there that will work with osx mail?
And by the way, am I blind or has the search option disappeared for these forums?
Thanks, tim

Answer 1

they can try:
Open Mail.app,
Go to Preferences, Account, select Outgoing Mail Server (SMTP):, select the drop-down box "Edit" server List, click on "Advanced" button in the center, make sure the gmail User Name is input in the box (do not include @gmail.com), just the log-in name, make sure the password matches the password they set at gmail from the web interface. Also check and make sure the port for outgoing mail is set correctly, close windows and Save.
Optional:
They can also go to gmail.com and click on troubleshooting POP or IMAP whichever they are using and there is also a section on password resets including step-by-step configuration of Apple Mail 3.0
