I installed Postfix on an Ubuntu 14.04 server running Nginx. While I was installing it, I put the system email as 'info#mydomain.com' not realising that it would now think that this was a local mailbox. This email address is a gmail account and so the server needs to look at the MX records.
I'm guessing what is happening is that it sees that its a local address and just sends it locally. I sent a test with:
echo "This is the body of the email" | mail -s "This is the subject line" info#mydomain.com
And sure enough in /var/mail/root there was a message:

I'm not sure how I can get the server to send the emails to the right place? Should I change the system email to something random?
I'm guessing that you've probably got the machine installed with mydomain.com as the hostname and so Postfix is configured to think it's answering email for mydomain.com. You probably want to edit your /etc/postfix/main.cf and remove your domain from the mydestination line there. (And then restart Postfix.)

I have read (https://support.google.com/mail/answer/12096?hl=en) that any Gmail account can receive emails for its plus alias.
So for account#gmail.com when I send email to alias+account#gmail.com
I receive following reply:
Delivery to the following recipient failed permanently:

Do I need to enable something? Or this functionality is no longer available?
You need to put it the other way around, so instead of alias+account#gmail.com, use account+alias#gmail.com.
My application uses PHPMailer to send email through gmail. It was previously working fine, but it appears maybe now gmail is categorizing my email as spam before it is sent out to the recipients. Below is an example of one of the messages that were rejected. I removed URL and Email addresses to protect the innocent. Is this as simple as making t he email body text better so it isn't seems as spam, or is there a more precise fix for this?

i have a problem with sending email from my server to hotmail and gmail. seems the mail is just dropped, no returned bounce email notices etc. the emails just vanish. I have looked around for solutions on the net but nothing seems to help. below are the email headers of one mail which is send correctly to another big provider, without any problem. As i cant make any sense of it as to why hotmail is rejecting these mails, i hope someone can make something of it and give me directions on maybe a solution:

I have dkim installed, tested all settings with mxtoolbox (dns, smtp etc) al seems to be right, but still Hotmail and Gmail is not accepting emails from my server (which holds about 25 domains, all sending through this server).
thanks!
Gmail ending up in spam is related to designated user not being able to send out through main server. case you have server: mail.server.com and you are sending mail with my.domain.com, the spf record needs to hold the ip6 of mail.server.com in spf. Obviously rDNS needs to be correct. For the hotmail problem, this is purely microsoft. you can check up with support from outlook.com, but only thing you get is "we dont block your server, although some emails are filtered. this can be caused by mitigation time, which can take up to 48 hours". Thats it. No messages are returned, simply dropped. Maybe msn.com outlook.com and live.com are experiencing the same problem.
When people try and send me emails from Microsoft Exchange, they get this error. I don't really deal with email servers and I have no idea where to start though. Is this problem our side or their side? Or how would I go about fixing this issue?

Your key text is
"Remote Server returned '550 4.4.7 QUEUE.Expired; message expired'"
Try goggling on the "message expired" to help determine the exact cause.

How can i retrieve the SMTP response? Please help me
This does not look like an SMTP response to me, as an SMTP response would be of the form "XXX some message". What you copied in your question is the log output that the mail server writes out when accepting and delivering the message.
If you are on a Unix system and have access to /var/log, you're likely to find a file in there called mail.log or maillog which contains the info you were looking for.
