Question

Hello,

I am using Mail.dll for email login and mail operations. It is working fine if I login from my computer. But it's not working if location is change to another country. I have tried by disable firewall and antivirus. But still same result. I can not download emails.

What can be reason for that?

What is the exact error message and exception's stack trace?

Answer 1

Please examine the exception's message, as server is likely to inform you, why the connection was disconnected.

There are several situations when server may lock your account:

• you tried to login with incorrect credentials to many times,
• you are logging-in from a different location that you used to,
• your account doesn't have IMAP/POP3 protocol enabled

Usually logging-in through web interface is enough; sometimes a captcha must be filled (e.g. Google's unlock CAPTCHA)

However those situations/restrictions are server/email provider dependent and you'll need to contact your server administrator/email provider help page, to get information on how to proceed.

Here you can get more details on a connection attempt failed error, it also provides link to articles on enabling IMAP/POP3 protocols in Gmail and Exchange.
