Email delays from my Exchange 2013 server to gmail.com

Hi

I have an Exchange 2013 full service packed and running well, apart from emails to gmail.

We are getting delays of up to 24 hours due to gmail thinking we are a bulk sender and not complying with their guidelines.

I have checked the logs and cannot see any sign of bulk email or spam heading to gmail and i have also ran as many checks as i possibly can and all come back saying the server is fine.

We do not get these delays emailing anyone else.

Im really not sure where to go with this as users are getting unhappy (quite rightly) and im not sure what else i can do.

thanks

I would suggest using a smarthost for sending SMTP mail.  For example if you have TIme Warner cable as your ISP you can use their SMTP server as a smarthost.  Others you may have to contact them to see if they allow you to use their SMTP servers.
Agreed with ktaczala, also ensure your connecting IP address is not black listed in any RBL.

Use url http://mxtoolbox.com/ to check reputation of your connecting IP.

Hi, does your domain has  SPF and DKIM records already . If not configuring SPF and DKIM gives more compliance for mails from your domain.

it has spf but not dkim.  I dont have dkim on many other server either but dont have any issues.  Each time i look into setting up dkim it seems to be a lot of grief and also involves the user making changes to outlook?
