close to desperation Postfix/Dovecot everything BUT sending mail works.

Hi Guys,

Even though I'm new here. I do have some time under my belt with Linux, Mailservers and such.

But I'm completely stuck
And I feel kind of daft for coming to ask but I seem to be the only one having this problem.

My postconf -n:

CODE -->

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
compatibility_level = 2
default_transport = smtp
home_mailbox = Maildir/
inet_interfaces = all
inet_protocols = all
mailbox_size_limit = 0
mydestination = formule1.demon.nl, localhost.demon.nl, localhost, armintangelder.nl, stormtangelder, stenntangelder
myhostname = formule1.demon.nl
mynetworks = [::ffff:]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/server.crt
smtpd_tls_key_file = /etc/ssl/private/server.key
smtpd_tls_protocols = !SSLv2, !SSLv3
smtpd_tls_security_level = may
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_domains = nxtgenracing.co.uk
virtual_alias_maps = hash:/etc/postfix/virtual 

My dovecot -n:

CODE -->

# 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.16 (fed8554)
# OS: Linux 4.13.0-37-generic x86_64 Ubuntu 17.10 
auth_mechanisms = plain login
login_greeting = Dovecot ready.
mail_location = maildir:~/Maildir
namespace inbox {
  inbox = yes
  location = 
  mailbox Drafts {
    special_use = \Drafts
  mailbox Junk {
    special_use = \Junk
  mailbox Sent {
    special_use = \Sent
  mailbox "Sent Messages" {
    special_use = \Sent
  mailbox Trash {
    special_use = \Trash
  prefix = 
passdb {
  driver = pam
protocols = imap
ssl_cert = </etc/ssl/certs/server.crt
ssl_key =  # hidden, use -P to show it
userdb {
  driver = passwd

I did not do to much work in my master.cf nor my main.cf
But if needed just shout.

I've been at it for days, googled my hind side off.

Problem is...

I receive mail, I can see everything, I can connect, I can read. But sending gives me just one error:

Connection to the server failed or was dropped. error code: -3253 (Outlook client on mac!)

EDIT: And my previous mail server worked like a charm but was on OSX. My ISP is not blocking any ports!

Nothing in mail.log, mail.err, syslog or anything in any log about something not working..

Help is very much appreciated.


Now beam down my clothes Scotty.. very funny!

RE: close to desperation Postfix/Dovecot everything BUT sending mail works.


And then it HIT me.... My processes where still Chrooted... changed it solved it...

Sorry... But as stated.. I probably was at it to long... To see my obvious mistake.

Master.cf is changed.


Very funny Scotty, now beam down my clothes
