I have 2 users on an iMac. The Os is Snow Leopard (OSX 10.6.8, Apple Mail) We had no problems when we used Eudora but need to move to a newer OS so we changed.
I have no trouble sending e-mail from the primary user but can't send from the secondary user.
we don't use verizon mail because we have our own domains and use godaddy as our host.
verizion help has been of little help and when I aske to be raised to a higher level I wa told I would get a call that was 2 days ago.
anybody have any suggestions
I agree that Apple support might be able to more easily identify the problem. However, while I'm not really a Mac kind of guy, given the symptoms the OP described, I would compare the settings for each of the two users' email accounts and see if any difference jump out.
I'd particularly look at ports being used, servers being used, user name and password entered, etc.
If any of those are different, changing the second user's setting to those in use by the first user may fix the problem.
If you are using Verizon's SMTP servers, then your settings should look something like this:
Outgoing Server: smtp.verizon.net
Server Requires Authentication: Yes
Requires a Secure Connection (SSL): Yes
If you are given the option anywhere for Secure Password Authentication (SPA), set it to No or Normal
These settings should work unless you have a Verizon/Yahoo account, in which case the server name would be outgoing.yahoo.verizon.net
If all of that is set up and it's still not working, your best bet is to provide a screenshot of your settings (with personal information blocked/removed) and any errors you are getting.
