Hello,
I have 0.9.4 version iRedMail on my server(debian 8.4)
I have issue when I try send to my server mail from one account.
When I send mail from this domain to my I got this mail :

Subject: Undelivered Mail Returned to Sender

This is the mail system at host sender.server.com.

I'm sorry to have to inform you that your message could not be delivered to
one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can delete your own
text from the attached returned message.

                   The mail system

<witold@recipient.server.com>: conversation with recipient.server.com[ip_this_server]
    timed out while receiving the initial server greeting

Final-Recipient: rfc822; witold@recipient.server.com
Original-Recipient: rfc822;witold@recipient.server.com
Action: failed
Status: 4.4.2
Diagnostic-Code: X-Postfix; conversation with recipient.server.com[ip_this_server]
    timed out while receiving the initial server greeting

relate this information I find in google this suggestions:
1)

echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
and restart postfix

2)

echo smtp_connect_timeout = 120s >> /etc/postfix/main.cf
and restart postfix

I do both this changes on my server but I still don't got mail from this account.
What I should check on my site ? In /var/log/mail* I don't have nothing about mail from this address...
This is issue on my site or on server who sent mail ?

Re: timed out while receiving the initial server greeting

*) Did you see any error in Postfix log file right after restarting Postfix service?
*) Any related log in your Postfix log file when you get this error?

Re: timed out while receiving the initial server greeting

when I start postfix in mail.log I have only this information

Aug 22 21:54:10 mail postfix/master[8622]: daemon started -- version 2.11.3, configuration /etc/postfix

mail.warn is empty, and I don't have mail.err file in /var/log directory.

On mail.log I don't see any error on time when I got mail with error.

Re: timed out while receiving the initial server greeting

No idea yet, have to debug it with direct ssh access. Would you like to buy a support ticket?

Re: timed out while receiving the initial server greeting

thanks, but this is not production server. This is my server where I can understand how works iredadmin. I don't want buy ticket.
This iredadmin in installed on fresh debian installation. Step by step with documentation.
