Finally my GMail hosted account problem regarding the use of POP3 and SMTP has been resolved after sending some information including some screenshot to the Google Apps team. They did the job quite fast although it.take one day to get reply from them but i’m really satifsfied that they can fix the problem. Other than that i really like the support team of Hostgator because when i request to make a change to my domain MX record, they did it in extremely fast speed (less than ten minute), also when i ask them to put the SPF record to my domain name because i don’t want my domain get blacklisted because of false report about sending spam mail, they did the job in less than 5 minute.
By the way, if you want to use a Google Hosted Mail service, all you have to do is replace your current MX record with GMail MX record like below :
reaper-x.com. IN MX 1 ASPMX.L.GOOGLE.COM. reaper-x.com. IN MX 5 ALT1.ASPMX.L.GOOGLE.COM. reaper-x.com. IN MX 5 ALT2.ASPMX.L.GOOGLE.COM. reaper-x.com. IN MX 10 ASPMX2.GOOGLEMAIL.COM. reaper-x.com. IN MX 10 ASPMX3.GOOGLEMAIL.COM. reaper-x.com. IN MX 10 ASPMX4.GOOGLEMAIL.COM. reaper-x.com. IN MX 10 ASPMX5.GOOGLEMAIL.COM.
If you don’t have access to edit the zone file, just open your host control panel, and search for option to change the MX record. But if your host using CPanel then you can add the first line to the Mail section under change MX record or something like that, and ask your host to add the rest. But don’t forget to ask your host to insert the SPF record too unless you want every email you send considered as spam. If you’ve reseller account (by using WHM or similar tools like that) or your host give you access to edit zone file, then you can edit it manually without asking them first. Simple isn’t it ?
