Dovecot / Dovecot auto restart (watchdog)
« on: July 23, 2021, 07:03:01 AM »
Due to backup unfortunately the server was briefly left without space and at that point dovecot service stop in the night around 00:57 min.

The server had free space soon after the backup, and in the morning at 08:00am when I checked, there was currently 20GB of free space on the server, but of all the services only the dovecot was not running.

Does the centos webpanel have some watchdog that monitors services that don't work so that it can autostart them, and how come the dovecot isn't started?

Tnx.

Code: [Select]
dovecot STATUS
dovecot.service - Dovecot IMAP/POP3 email server
Loaded: loaded (/usr/lib/systemd/system/dovecot.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Pet 2021-07-23 00:57:49 CEST; 7h ago


dovecot.log

E-Mail / Re: CWP is duplicating domains lines in vmail_ssl.map
« on: July 15, 2021, 07:43:20 AM »
Did it help?

I noticed that every night at 4:00am vmail_ssl.map is generated, obviously via cron.
But there is maybe some bug in those vmail_ssl.map creation because again there are double lines in vmail_ssl.map and because of that vmail_ssl.map.db isn't created. So again annoying warning in maillog:

"warning: database /etc/postfix/vmail_ssl.map.db is older than source file /etc/postfix/vmail_ssl.map"

Anyone knoww what is creating this vmail_ssl.map file?

Yes, I also noticed that. I sent them a question, but they do not respond with a solution if you don't pay.
It isn't problem to pay to solve problems, but I noticed that when I pay they only solve my current problem on my server (temporary fix) not future problem or maybe even to fix a bug.
So you don't know what was the problem or is it fixed and you aren't sure that this problem will not occur again in few weeks or months.
Thatís why I tried to find a temporary fix myself.

Anyway, there are maybe some bugs in SSL creation and also with vmail_ssl.map creation and those double lines.

FIX:
I fixed today with manually checking what was the double lines in vmail_ssl.map files, and then in web panel >
WebServer settings > SSL certificates select Admin services for first double entry in vmail_ssl.map and turn on: FTP and CPANEL services. There is a bug because cpanel isn't added, just ftp, no matter, but that fix all doubles in vmail_ssl.map and vmail_ssl.map.db is created.

Anyway, just renew of SSL didn't help in first attempt. In 2nd I requested admin services cpanel and ftp.
For now it is fine.

I have the similar problem, but generating database isn't possible with this command
postmap /etc/postfix/vmail_ssl.map

because I'm getting this:
postmap: warning: /etc/postfix/vmail_ssl.map.db: duplicate entry: "webmail.somedomain.com"
postmap: warning: /etc/postfix/vmail_ssl.map.db: duplicate entry: "mail.somedomain.com"
postmap: warning: /etc/postfix/vmail_ssl.map.db: duplicate entry: "webmail.somedomain2.com"
postmap: warning: /etc/postfix/vmail_ssl.map.db: duplicate entry: "mail.somedomain2.com"
etc...

And it is right, this file vmail_ssl.map has really double entries, but why?
It is generated at night, so I guess there is some bug that is generating double lines.

Is this a bug?

Maybe your localhost/server is not allowed to send email.

Check:
/etc/postfix/main.cf
and add permit_mynetworks to smtpd_recipient_restrictions example:

smtpd_recipient_restrictions =
    permit_sasl_authenticated,
    permit_mynetworks,
    reject_unauth_destination,
    reject_non_fqdn_sender,
    reject_non_fqdn_recipient,
    reject_unknown_recipient_domain,
    check_sender_access hash:/etc/postfix/sender_access
    ,reject_rbl_client zen.spamhaus.org
    ,reject_rbl_client bl.spamcop.net


and add to /etc/postfix/mynetworks file
127.0.0.0/8

Reload postfix with:
systemtl reload postfix.service

The best way to check number of spiders/crawlers to your server is this command:

cat /usr/local/apache/domlogs/*.log | awk -F\" '{print $6}' | sort | uniq -c | sort -n
or
cat /usr/local/apache/domlogs/specific-domain.log | awk -F\" '{print $6}' | sort | uniq -c | sort -n

Also you can firstly clean all of your logs and get "new/fresh" result:

Beware, this command truncate all logs to empty:
find /usr/local/apache/domlogs/ -type f -name "*.log" -exec truncate --size 0 {} \;

With this command you can check which logs will be deleted first:
find /usr/local/apache/domlogs/ -type f -name "*.log" -exec ls -if 0 {} \;

CentOS 7 Problems / Re: SSL and Email Problem Cpanel to CWP Migration
« on: February 14, 2021, 11:46:29 AM »
It is possibly working for you domain.com but not for www.domain.com.
All you need to do is to add A record in your DNS.

Remove CNAME for www and add A record for your domain with your IP address.

Example:
www 14400 IN A %ip%

Request SSL again.
