Google domain email won't send mail though apple mail

Question

I just setup a new goole domain email address and have been fully varified with my domain. I set up the account on my imac & macbook pro, both running off Mavericks. I can receive email but not send and I keep getting asked for my email password. It's been entered in correctly. The mail just sits in the outgoing mailbox. The strange thing is that the same email account send emails perfectly from my iPhone. I have searched the issue and it seems to be a common issue with Mavericks however I haven't been able to find one solution that works. Can someone please office some advice? Feeling very frustrated right now! Thanks

I just fired up a new macbook air and had the same issue - set up my google domains email account and received emails but could not send. Strange as we have many Apple devices and they all work fine. Here is how I sorted it.
In summary the username used in the STMP server list (which was automatically populated with data on set up) was incorrect. It needs to be set to your full email address - mine just showed my name and no @domainname.com . See below if you need  step by step instructions on how to change it.
Open mail and in the main menu bar at the top of the screen click on mail then preferences. Click on accounts in the menu at the top of the panel that opens and then select the offending account in the list on the left.
In the section labelled Outgoing Mail Server there is a menu which is usually defaulted to gmail - click and open this and then select Edit STMP Server List.
In the new page that opens about half way down you can select advanced. When you click on this there is a panel near the bottom marked username. This was the problem. It had automatically set itself to the first part of my email address without the @nameofdomain.com. When I reset this to read my full address all worked fine.
I hope this sorts your problem as I know what a total pain in the *ss this can be!
