Dovecot "Status=deferred" [Ubuntu 9.04]
Nov 9, 2009
I am trying to set up a mail server with postfix and dovecot. However I am getting a status = deferred error instead of status = sent in my log and the mail will not be sent. Sending a mail to hotmail/gmail works fine though.
I used this tutorial [url]
And later updated to the Lenny tutorial [url]
The mailserver is running on Ubuntu 9.04 (desktop/32bit).
Log
Code:
Oct 24 14:29:19 pws-desktop postfix/qmgr[17007]: C01F71FE146: from=<steve@example.com>, size=341, nrcpt=1 (queue active)
Oct 24 14:29:19 pws-desktop postfix/pipe[17035]: C01F71FE146: to=<john@example.com>, relay=dovecot, delay=0.22, delays=0.15/0.01/0/0.06, dsn=4.3.0, status=deferred (temporary failure)
The OS is running on a Dell 1600SC.
Ubuntu 9.04 Desktop x86
Kernel: 2.6.28-16 generic
Dovecot: 1.1.11
Postfix: 2.5.5 (both provided by the ubuntu server team and installed using synaptic)

I am opening this thread to complain about Yahoo mail issues with our ISP. Its been a month that we are having problems trying to send e-mail to Yahoo accounts.
First of all we are a Web Hosting company in Brazil and the IP that they blocked only host our main domain maxihost.com.br. We dont send bulk ou spam e-mails, we only send invoices and support replies to their accounts.
The logs from our mail servers when trying to e-mail them is below,
Code:
LOG: MAIN
cwd=/usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -v -M 1KHPUv-0007rp-0r

Note that I already filled out the form
[url]telling them I am an ISP and I do not send any e-mail spam for their accounts, although every time I fill it I get an automatic/canned e-mail from their system with the following content,

I am tired of fighting yahoo and their horrible email policies.
I have some users that run contests and send weekly mailers to a large number of users on yahoo.. Well every time they send out their mailers (keep in mind they are not spam) yahoo decides to greylist our servers. I guess this is yahoo's way of attempting to block spam but then why is our "non spam" mail being deferred?
I am just really tired of having 10k emails in my mail que that are retrying throughout the day because yahoo deferred them. It's causing higher server loads and wasted bandwidth.
The error messages read:
Please refer to[url]
So I go there.. make sure we are following their communist guidelines, and fill out the form only to be greeted with an automated response. Nothing else from yahoo, evidently they want $25/hr to fix the issue.. Extortion!
Todays dilbert is spot on...

way to create a VPN tunnel between two ubuntu servers?
Both will be in seperate datacentres but I'd like a secure tunnel so I can setup jobs to backup to one another.
This has to be done on the server level and cannot be done at the router/firewall as I do not have access to this kit.

i started experiencing inconsistencies in mail delivery, getting only 50-60% of all mail.
I have php that generates confirmation emails that are later sent to administrator.
I know that php part is working fine but when it comes to sendmail we have a problem.
Jun 2 12:19:14 xxxxxx sendmail[32659]: m52GJDRo032659: to=xxxxxxxxxxxxx@comcast.net, delay=00:00:01, xdelay=00:00:00, mailer=relay, pri=47870, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection reset by [127.0.0.1]
the last part " stat=Deferred: Connection reset" is where i think the problem is.
What can be the reason for connection reset?
just in case here is my top

i recived below email from my server!
what is this and what should i do i don`t use any SSL
Certificate for dovecot on server.test.com was expired and a self signed one was created to replace it. You should install a new certifcate as soon as possible to replace the self signed one that was installed to replaced the expired one. You can install a new certificate in WHM under "Manager Service SSL Certificates", or by clicking this link: [url]

I have a what seems like a quick question. I'm hosting my own DNS servers via bind, and everything seems to be nice and dandy. However, I cannot seem to receive email, and when I do a check via pingablity it tells me there is a timeout error when trying to reach my MX record. I *am* able to access the POP/IMAP server (which is powered by Dovecot) through Outlook and other email clients.
I know it is an issue with iptables because as soon as I turn it off pingability is able to reach my mail server just fine. I do have port 53 open as well as 1024-65535 UDP ports open. I've scouted internet for hours trying to find the cause of the problem with no results.

This is a fresh installation in AWS using AMI for Plesk 12.
When installed with Dovecot I got this error when trying to login to mail:
Jun 28 12:23:44 server1 dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<someuser@xxxxx.com>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured, session=<mfryjpUZdgB/AAAB>
If I switch to Courier works perfect:
Jun 28 12:35:53 server1 courier-imapd: Connection, ip=[::ffff:127.0.0.1]
Jun 28 12:35:53 server1 courier-imapd: LOGIN, user=someuser@xxxxx.com, ip=[::ffff:127.0.0.1], port=[35677], protocol=IMAP
Jun 28 12:35:53 server1 courier-imapd: LOGOUT, user=someuser@xxxxx.com, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=52, sent=156, time=0
In normal servers or under Virtuozzo (formerly Parallels Cloud Server) Dovecot works without problem.

on a fresh debian 7 64bit openvz system we actually have a problem with the new plesk 12 feature of limiting outgoing mails.We migrated about 25 systems to plesk, this is the first that makes problems.If limiting outgoing mails is activated (i double-checked all possible checkboxes in plesk) a fresh mailbox gives us the following error while trying to send via smtp:
Aug 15 13:09:32 2d4 postfix/smtpd[8645]: connect from unknown[XX.XX.XX.XX]
Aug 15 13:09:32 2d4 postfix/smtpd[8645]: E9AF61C58851: client=unknown[XX.XX.XX.XX], sasl_method=PLAIN, sasl_username=XX@XXX.XX

Aug 15 13:09:32 2d4 /usr/lib/plesk-9.0/psa-pc-remote[8611]: handlers_stderr: SKIP
[code]....
After deactivating the feature all mail is sent without any problems. We use postfix + dovecot.

I did the following configuration:
Postfix
in the /etc/postfix/main.cf I added the following configuration parameter
recipient_delimiter = +
Managed a sieve script in webmail which contains the following:
1: # Sieve Filter
2: # Erzeugt von Ingo (http://www.horde.org/apps/ingo/) (03.02.2015, 02:53:39)
3: require "fileinto";
4: # Plustest
5: if address :all :comparator "i;ascii-casemap" :contains "To" "+plustest" {
6: fileinto "INBOX.plustest";
7: stop;
8: }
I created a folder in my INBOX with the name plustest, now I sent me an email from an outside freemail-account to see if it works. In the logfile /var/log/maillog I can see the following entry:
Feb 3 15:06:25 mail postfix-local[18290]: cannot chdir to mailname dir <name>+plustest: No such file or directory
Feb 3 15:06:25 mail postfix-local[18290]: Unknown user: <name>+plustest@<dom.tld>
Feb 3 15:06:25 mail postfix/pipe[17708]: 0ECAF4C1B3: to=<name+plustest@dom.tld>, orig_to=<aliasname+plustest@dom.tld>, relay=plesk_virtual, delay=0.61, delays=0.52/0/0/0.09, dsn=2.0.0, status=sent (delivered via plesk_virtual service)
I changed my real name to <name> and my domainname to <dom.tld> in this post.

Ubuntu 14.04 with Plesk 12 (10 Domain License).Using this for mail only... multiple domains.Postfix and Dovecot installed. Trying to figure out how to do:
- SASL Auth (Dovecot)
- TLS
- want above two to be mandatory... no plain text auth and no unencrypted connections.
How do I achieve this with Plesk 12?I have found countless how-to's about doing this with Vanilla (non Plesk) installs with the same server software. However, Postfix main.cf and master.cf both appear to have specific Plesk modificatuons. Same thing for the related Dovecot conf files... also have Plesk specific modifications.
I see no way to enable the desired settings from the Plesk Panel. Can't achieve this within the Panel but also can't modify the conf files without potentially breaking some Plesk-specific functionality? My original hope in purchasing the Plesk license was to make administration of the mail server easier. Unfortunately, I'm struggling to do this now and may have already had this figured out had I not bothered with the Panel.

I just upgraded from Plesk 11.x to 12.0.18 and was eager to try the new sieve functions. I used the normal Plesk Updates/Upgrades tool to change the imap server from Courier to Dovecot. However, Dovecot will not start. It gives an error about /etc/dovecot/private/ssl-cert-and-key.pem missing.

i use Plesk on a vserver which was offering it in version 11.x, i upgraded to 12.0.18, then i installed Dovecote on the panel. Everything went fine. Mail server is working.BUT sieve does not allow me to login and create filters.I tried telnet against 4190, and it works:
Connected to mail.xxxxxxxx.xxx.
Escape character is '^]'.
"IMPLEMENTATION" "Dovecot Pigeonhole"
"SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags notify"
"NOTIFY" "mailto"
"SASL" "PLAIN LOGIN DIGEST-MD5 CRAM-MD5"
"STARTTLS"
"VERSION" "1.0"
OK "Dovecot ready."
But when i use my sieve plugin for thunderbird OR access plesk's webmailclient Roundcube opening the filter module, it doesnt work. On Thunderbird i see the loading animation, thats it. On Roundcube it says "Unable to connect to sieve server".
Looks like something is missing. I can definitely access 4190 on my server from anywhere. So no firewall issue. I didnt change anything on configs, since plesk is handling it.Roundcube log doesnt give me anything. I dont even see logs added (to syslog or mail.*) while i try to connect.

if i create a new mailaccount in the power-user panel and i dont log in into the webmailer, so the "subscription" file is not created.
that means there is no way to sent emails with the new created account with external mail clients (Thunderbird), because there is no "sent" or "drafts" folder.
the problem disappears, if i log into the webmailer after creating a new mailaccount.
is there any other way to fix this bug? i want plesk 12 to create the "standard" folders (Trash, Drafts, Sent, Spam) automatically.
something to the used system:
- Ubuntu 14.04 Server
- Plesk 12.0.18
- IMAP/POP3 Server: dovecot
- SMTP Server: postfix
(logfiles are not showing anything..)
