can't send mail with Mail.app, OS 10.5.8, and new verizon fios
We just made the switch to Verizon.
Setting up Mail.app with my relatively new MacBook Pro (and 10.8.4) was very smooth.
Not so with my wife's old PowerBook G4 running 10.5.8, which she inherited from my daughter.
It seems to set up fine, using the same settings for the servers as on the MBP (it has to be done manually), but it is unable to send mail (via the verizon smtp server). The Connection Doctor thing does not have any trouble finding the servers and connecting.
I get the "The sender address xxx@verizon.net was rejected by the server smtp.verizon.net." message.
These settings work when sending email from this verizon account from her iphone, or from my MBP.
I successfully set up my .me email account on the G4 and that was able to send mail.
Couldn't find anything online to shed light on this. Any help would be appreciated. Thanks
