Hi, everyone
I'm trying to enlarge mail attachment max_size up to 30mb using this article: http://www.iredmail.org/docs/change.mai … .size.html

I changed postfix config:
postconf | egrep 'message_size|mailbox_size'
mailbox_size_limit = 35000000
message_size_limit = 35000000

changed php.ini :
egrep 'memory_limit|upload_max_filesize|post_max_size' /etc/php.ini
memory_limit = 200M;
post_max_size = 40M;
upload_max_filesize = 40M;

and .htaccess file:
egrep 'memory_limit|upload_max_filesize|post_max_size' /var/www/roundcubemail/.htaccess
php_value   upload_max_filesize   40M
php_value   post_max_size         40M
php_value   memory_limit          200M

though i don't use apache:
netstat -ntlp | egrep '80|443'
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1718/nginx: master
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      1718/nginx: master

i changed nginx config too:
grep client_max_body_size /etc/nginx/nginx.conf
    client_max_body_size 40m;

I restarted all related services, dovecott including; i restarted even server and rechecked config files - everything is on its place, but when i try to send e-mail with 29mb-attachment I get error: SMTP Error: Message size exceeds server limit

So where can I change this limit?
kindly ask to point me where i'm wrong or not enough attentive

PS: I've forgotten to say I don't use SoGO, Roudcube only and Outlook (which i failed to tweak yet too, but that's another question)

regards,
Nick
