I have been using some SMTP server for sending mails to gmail server. The problem i am facing is all the mails from a particular domain(say ...#somedomain.info) are treated as Spam by gmail. Is there any way to solve this issue?
Have you analyzed your outgoing mails? What SpamAssassin score do they get if you send them to a server with a SpamAssassin filter?
Normally your issue indicates a wrong mail server setup. Wrong DNS setup, blacklisted on DNSBLs, invalid DKIM or SPF setup, invalid headers or mail encoding, ...
But at first you have figure out what the root cause is. You only stated the impact. And SpamAssassin tests hundreds of rules for many common mail problems. So knowing the rules that get hit lead to finding the cause(s).
If you like you could write a mail to mailtest[AT]malowa.de and I will analyze the score.

As of yesterday, I can't send any emails with gmail as my alias with network solutions. Has anyone found a fix for this?
I get the error on gmail:
Message not delivered
You're sending this from a different address or alias using the 'Send mail as' feature. The settings for your 'Send mail as' account are misconfigured or out of date. Check those settings and try resending.
TLS Negotiation failed, the certificate doesn't match the host.
Try to enter to https://accounts.google.com/b/0/DisplayUnlockCaptcha

Using src html and url image from webserver, can the server get the message-id from the email header?
Or, is it possible for an URL to only work with a particular email message?
Ben
No. When an HTTP server gets a request initiated by the user loading remote images in an HTML formatted email, there is no way for it to identify the email.
The closest you could come would be to use unique URLs on a per email basis but that suffers from two flaws:
It might be flagged as tracking code and used to increase the spam score of the email
The URL can be copied by anyone with the email (including by forwarding the whole message) and reused elsewhere

I have a #mydomain.com and via Gmail Google Apps for business. It was down for 2 days so I did not receive emails that bounced from clients. Is there anyway to get those messages now that the email is back up?
The answer to this would completely depend on why the emails were bounced.
For example, if your MX records weren't pointing to Google's servers, no, this wouldn't be possible in Apps as the messages never hit Google's servers to begin with. You will need to reach out to any clients that you suspect received bounce messages and ask them to resend them.
Some DNS providers also offer email spooling services in the event of some DNS setting causing failures to deliver messages, etc. You would need to contact them to check on this though.
If the mails were making it to Google's servers but Apps was bouncing them for some reason, you can check the Email search log to find the bounced messages.

I started creating online open source game as a project in school. It will be server with n connected clients. But now I have a problem with "security". What to do if one client would used modified source code for changing some restrictions? How can I prevent it? My first idea was make client only for connection to server and server would send all necessary files but I don't like this idea very much. Can you advise me something better? Thank you.
You need to keep your validations in the server. The server should check each client move, and if it's not allowed according to the server's rules - reject it.
You should still keep validations in the client, too, so that users who don't mess with the client code can get speedier responses.

Is it possible to capture the failure mail. I have created a application for sending mail, i have a log file to store the sent mails. If the sent mail is failure, i just want to find out the failure mail and update the log file.
Is it possible! Is there any way to match the sent mail and the failure mail
Please help me and guide me.
If you mean by failure, a bounced email, you can add an email address to 'return-path' header. If the email is bounced it will be returned to the the email address specified in the return-path. You can then set up a service to analyze these emails.
You have to specify what client are you using, is it Postfix, sendmail, etc?
And what do you mean by "failure".
The basic approach would be to use crontab. It can direct error message
to your email, when it fails
MAILTO=youremail#foo.net
#
# run five minutes after midnight, every day
5 0 * * $HOME/bin/emailcode
If you use sendmail, you can always
verify the log at:
/var/log/maillog
