Mail not receiving in webmail from gmail - gmail

I am using 1and1 server. It is hosted in plesk panel. My mails from webmail are getting receiving in spam and when I am sending a message from gmail it is not receiving to webmail. Where is the problem?

Is your mail IP is blacklisted in spam databases ? Please check mail IP status at http://mxtoolbox.com/blacklists.aspx
And enable SPF and domain keys for your domain so that your mail will not receive in spam folder

Gmail DMARC error for sending mail from another domain

I have domain on google like mydomain.com, but I'm sending emails from mailgun where domain is mg.mydomain.com.
Now I have error with DMARC.
Is there some way to let mg.mydomain.com send emails with mydomain.com domain? Or some another to avoid this problem?

Send authorized email in behalf of xxx#domain.com from a server that hasn't that domain

I'm using PHPMailer on PHP on Apache2.0 on Unix with sendmail to create a webservice that can send emails to some customers.
This server doesn't have a domain and the email will have "From: xxx#domain.com" header as they will be sent in behalf of the mother website (let's say domain.com).
Now, everything works, but Gmail and Hotmail detect my email as spam.
It seems legit as there is currently no correlation between the sender server and the mail sender address.
What do I have to do to tell google that the email are authorized?
How do I have to set an SPF record for domain.com ?
Thank you

Amazon SES SMTP same content sent to the same email service (gmail.com) different results

I'm sending a newsletter and testing it when I try to send to 2 google accounts
account1#gmail.com and account2#gmail.com
Why does my email go the inbox of account1#gmail.com while account2#gmail.com is sent to spam?
NOTE: (same newsletter content are sent, account2#gmail.com was receiving the newsletter in the inbox before but now it's not. I did not touch any filtering of gmail)
DKIM and SPF are all set up except DMARC
I'm suspecting maybe the SES SMTP IP I'm using is blacklisted but I'm curious does amazon SES choose the SMTP IP the email will be sent according to it's spamminess?
example:
If SES sees a spam on the sent email content it sends using their IP addresses that are blacklisted?

Mail server running sendmail cannot receive incoming mails

I have a server which is hosting a web site. I want to enable using emails using the domain name (e.g. xxx#mydomain.com), so I configured email service using sendmail and dovecot. I am new to configuring email servers, and currently I met with two strange problems. I am seeking for your kind help:
Regarding sending mails to external email addresses defined in /etc/aliases:
in the /etc/aliases file, I define a group which direct incoming mails to both my local email account and to my external email account, e.g.
admin: myname#mydomain.com, myname#mycompany.com
When I login to my server and send mails to admin#mydomain.com, both emails can be delivered. However, when I use external mail servers to send (e.g. myname#mycompany.com), only #mydomain.com mail can be delivered, and I got a reject message for #mycompany.com mail:
sender address rejected: Access denied
I have already enabled FEATURE(`relay_based_on_MX')
I cannot send mails to myname#mydomain.com using web-based emails like gmail, hotmail or yahoo mails. After a few hours (sometimes one day), I got delayed delivery message from web emails. e.g.
(from gmail)
Delivery to the following recipient has been delayed:
myname#mydomain.com
Message will be retried for 2 more day(s)
Technical details of temporary failure:
The recipient server did not accept our requests to connect. Learn more at http://support.google.com/mail/bin/answer.py?answer=7720
[(10) mydomain.com. [xxx.xxx.xxx.xxx]:25: Connection refused]
I have already configured firewalls to allow needed ports (e.g 25, 143, 110). And I can the mails sent from #mycompany.com can be delivered.
I suspect the web mail servers may require extra verification. What other configurations should I do to enable my mail server receive external mails?
Thank you for your attention!
