After upgrade to Yosemite 10.10.4 unable to send with smtp.gmail.com
I have two Gmail accounts, one personal and one with my university. Until I upgraded to Yosemite 10.10.4, and using AppleMail sending and and receiving worked normally. Now I can only receive. I've deleted and re-established these two Gmail IMAP accounts to no avail. Suggestions on next steps to resolve the issue would be appreciated.
