I really need to be using my Google Apps SMTP server for outgoing mail on my site and it's a user heavy site, so this is often.
The problem is that currently it takes 1-2 hours for an email to send/be received which causes non-stop support enquiries about 'I've registered but haven't received my password yet' and generally doesn't look good.
I've tried three SMTP plugins - WP SMTP, Configure SMTP and Cimy Swift all with the settings which Google Apps provides;
However they are all returning the error 'cannot connect to server - 111'
These settings work in outlook to send Google Apps emails, so what's the problem with WordPress?
I would be great if anybody has set this up on their site and they can share the secret??? :)
