Problem while sending a mail from hosting server using Google apps account.

[Jaydeep Ramavat]

Dear friends,

I have one google apps email account.
I am sending a mail through the ASP.NET application.

When i sent it from local network where internet access is available, it successfully delivered at target email account.

But when i uploaded this thing to Hosting Server I am following error.

A socket operation was attempted to an unreachable host IPADDRESS:587

if you have solution, i request you to share.
Thanks
Jaydeep.

So you are asking "How can I send email from a location that doesn't allow email access?"

I admit this area is out of my comfort zone, but if it works from one location with unrestricted access then your application is fine. If it fails to work from another location where they have restrictions then there isn't much you can do.

Would some other expert with more experience chime in, or does that sound about right?

I found one solution.

Just Replaced the Port Number from 587 to 25, and it worked.
I think port 25 is default for SMPT and it is available on hosting environment.
