Hello everyone! Something wrong with my server, after upgrade from 0.90 to 0.91.

When I send mail to some servers, I get a letter of response:

Jun 16 11:17:19 mail postfix/smtp[9755]: CD98A60218: to=<remoteuser@domain.com>, relay=relay.domain.com[211.222.50.34]:25, delay=2.9, delays=0.05/0.02/2.5/0.24, dsn=5.0.0, status=bounced (host relay.domain.com[211.222.50.34] said: 550-Verification failed for <myuser@mydomain.ru> 550-Called: 90.200.110.204 550-Sent: RCPT TO:<myuser@mydomain.ru> 550-Response: 554 5.7.1 <myuser@mydomain.ru>: Recipient address rejected: Policy rejection 550 Sender verify failed (in reply to MAIL FROM command))

Log on Remote Side:

On the old version of IredMail (0.90) everything works: What I did to upgrade:

File: /etc/iredmail-release
0.9.1

1) Upgrade Roundcube
apt-get update
apt-get upgrade

apt-get install php-pear php5-intl
php5enmod intl
service apache2 restart

cd /tmp
tar xf roundcubemail-*.tar.gz

mysql -u root -p
use roundcubemail;
GRANT ALTER ON `identities` TO 'roundcube'@'localhost';
\q

cd roundcubemail*
./bin/installto.sh /usr/share/apache2/roundcubemail

cd /usr/share/apache2
mv /usr/share/apache2/roundcubemail-1.0.4 roundcubemail-1.1.1
rm -i /usr/share/apache2/roundcubemail
cd /usr/share/apache2/
ln -s roundcubemail-1.1.1 roundcubemail

2) Fixed: return receipt response rejected by iRedAPD plugin reject_null_sender

nano /usr/share/apache2/roundcubemail/config/config.inc.php

$config['mdn_use_from'] = true;

service apache2 restart

3) iredapd

cd /root
tar xjf iRedAPD-*.bz2
cd iRedAPD*/tools/
bash upgrade_iredapd.sh

4) iredadmin

cd /root/
tar xjf iRedAdmin*.bz2
cd iRedAdmin*/tools/
bash upgrade_iredadmin.sh

5) Bypass greylisting for some big ISPs

cd /tmp
wget https://bitbucket.org/zhb/iredmail/raw/ … telist.sql

mysql -u root -p
mysql> USE cluebringer;
mysql> SOURCE /tmp/greylisting-whitelist.sql;

6)  drop retired column in Amavisd database!!!

mysql> USE amavisd;
mysql> ALTER TABLE policy DROP COLUMN spam_modifies_subj;
\q

7) phpmyadmin

cp -a /usr/share/phpmyadmin /tmp
cp /usr/share/phpmyadmin/config.inc.php /tmp
rm -rf /usr/share/phpmyadmin
cd /tmp
tar xjf phpMyAdmin-4.4.8-all-languages.tar.bz2 -C /usr/share
cd /usr/share
mv phpMyAdmin-4.4.8-all-languages phpmyadmin
cp /tmp/config.inc.php /usr/share/phpmyadmin
service apache2 restart

Please HELP!!!!
