I have a regular gmail account and a custom domain'd gmail account.I want to use Gmail's Check mail using POP3 function to retrieve the latter into my regular user@gmail.com but I cant get past this popup. It either says it had a problem connecting to pop.gmail.com or mail.customdomain.com timed out.One last note: I do not want to forward emails from one account to another.
Receive mail into Gmail from custom domain Google Apps
gmail;email;pop3
For gmail, the port should be 995 not 110.Also you have to make sure that pop is enabled on the account.However, as mjrider says, forwarding is much faster and it should cause any problems with conversation flow, providing you don't log into the secondary account directly and send emails from there (since these replies won't appear in your main account).I use both forwarding and pop access, but the latter is only for is an old account which I can't forward.
