Thunderbird Autoconfiguration

How to make Thunderbird know your configuration ports?
Thunderbird smtp/pop/imap auto setup.

The goal is to setup thunderbird by any non-tech with only 2 available information, i.e. username/email and password.

There is two ways of achieving this.
1) Provide mail server infrmation to mozilla database this could take forever and wait until they verify and update there database.
2) create a autoconfig and point (dns) somewhere.
probably the easiest.

How to achieve this. Its simple.

Create a xml called: config-v1.1.xml
Setup xml accordingly, (as your port is) and point autoconfig.domain.com into particular server. 🙂

Unauthenticated email is not accepted from this domain

Unauthenticated email is not accepted from this domain

from=ashishnepal@domain.com,addr=any@googlehosted.com: 550 5.7.1 Unauthenticated email is not accepted from this domain. v234s7598891wib

The cause of the problem is that:

Google rejects all mail from the @domain.com domain unless they are able to verify DKIM signature.

Solution :
Add your domain.com outbound mail servers’ IP addresses under “Inbound Gateway” in the domain settings for @googlehosted.com in Google Apps.

This way you could bypass the DKIM signature authentication (or google will simply accept even if its thats not accepted.)

Count number of mail sent out Each Hour
