Issue Send Mail Authentication Required

chrisbi

I hope this is the correct category. I have the following problem:

I am new with Kopano, bevor I used another Groupware Mailserver but now I want to change my mailserver to Kopano.

I installed Kopano with postfix and MySQL. The most function work well. I can receive Mails, connect to WebApp, connect with Z-Push… But I have a problem to send Mails to my old Mailserver. When I send a Testmail for example to iCloud there is no problem an status is “sent”, but if I send the mail to my old mailserver I get the following failure:

status=bounced (host mail.oldmailserver.de[X.X.X.X] said: 550 5.7.1 Authentication Required (in reply to end of DATA command))

I searched for a solution, but I think I can’t see the forest for the trees.

This is my Postfix main.cf:

smtpd_banner = $myhostname ESMTP
biff = no

append_dot_mydomain = no
readme_directory = no
compatibility_level = 2

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

relayhost = 
smtp_sasl_security_options = noplaintext noanonymous

smtpd_relay_restrictions = permit_mynetworks, reject_unauth_destination
smtpd_recipient_restrictions = permit_mynetworks,
			       reject_non_fqdn_recipient,
			       reject_non_fqdn_hostname,
			       reject_invalid_hostname,
			       reject_non_fqdn_recipient,
			       reject_non_fqdn_sender,
			       reject_unauth_pipelining,
			       reject_unverified_recipient,

myhostname = mail.newmailserver.de

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = localhost
mynetworks = 127.0.0.0/8, localhost
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

virtual_alias_maps = hash:/etc/postfix/virtual
virtual_mailbox_maps = mysql:/etc/postfix/mysql-users.cf
virtual_transport = lmtp:[localhost]:2003
virtual_mailbox_domains = newmailserver.de

I hope anyone can help.

to me it looks like the bounce response comes from your old mailserver. Maybe you should look there for the problem.

chrisbi

I don‘t think that is a problem of the old mailserver because i receive all mails from other Mailservers. So it must be a problem with kopano.

fbartels

I would concur with @xthbx. Maybe an overlap of domain names?

What groupware have you been using before @chrisbi? Your username feels familiar.

chrisbi

Ok @xthbx and @fbartels you were right. I found the issue, the domain I use on the Kopano Server was still stored as alias on the old mailserver. Thank you for the tip with the overlapping.

@fbartels I used Kerio Connect before and now I try Kopano, maybe it will be the successor.
