Thanks. I already knew this page. My problem is that i don‘t know what will happen... I set Plesk to split backup archives to 2048 MB each. Does it create at first ALL chunks and uploads them then to FTP? Then my server will crash as it has not enought space... OR does it upload the chunks...

Hi, quick question: I want to backup my server (453G total, 266G used, 164G free) to an FTP Space. The backup fails with the message "Not enough free disk space to backup selected objects. At least 236539.92 MBytes free disk space is required.". I thought as of Plesk Onyx 17.5 and above the...

Thank you! Didn't know about "MAILFROM".

Thank you but problem is not how to send emails via cron job, the problem is the FROM/SENDER address the emails get sent with.

Is there a way to change the "from"-address for cron emails? I get messages from "[email protected]", but I want from address to be "[email protected]". My full FQDN is "subdomain.domain.com" (also the URI where the plesk panel is accessible) which is also my /etc/hostname and...

Hello, my hostname: mars.example.com. I have multiple domains "exampl1.com", "example2.com" etc. with mailboxes. If I set a ssl certificate via Configuration => SSL/TLS-Certificates I can only secure the hostname / one mailserver address (mail.example.com) of the server. To allow all domains...

Because I thought that maybe some other non-PLESK services / programs can (mis-)use postfix to send spam f.e. I enabled Outgoing Mail Control-Feature already in PLESK limiting email sending to 300 for my domain (and disallow sendmail).

Ok. Thank you for clarification. But then there is the question why the iptables rule does prevent email sending. Because if the spawning processes run under the user postfix the iptables rule should work and let traffic pass through... Can you help me with an iptables rule which only allows...

Thank you for your answer. Ok I understand that master process must be running as root because of port bindings. But what about the spawning-processes (postfix does spawn new process if mails get send out, which should run as user postfix). I try to secure my server, especially the mail delivery...

Hello, I saw in master.cf file, that plesk configured postfix to run as root. # # Postfix master process configuration file. For details on the format # of the file, see the master(5) manual page (command: "man 5 master" or # on-line: http://www.postfix.org/master.5.html). # # Do not forget to...

Postfix was installed via PLESK. The question is how PLESK can use the via PLESK installed postfix with SMTP auth for sending emails as I deactivated sendmail completely. It would be the same case as if I would use an external SMTP server for sending ONLY PLESK mails and use the local (via PLESK...

Thank you. Yes, I want to configure PLESK to use an smtp server. But I also want to use postfix as smtp server not only the relay mentioned in the provided documentation section. To be precise: I want to have postfix with mailboxes on my server. I do not want to let anything (scripts, PLESK...

Hi, is there a chance to let Plesk sent administrator (backup finished, ssl certificates renewed, etc.) emails via smtp (postfix) instead of sendmail? Because I deactivated sendmail completely on my server to prevent spam. Sincerely Maximilian Füsslin

Yes but this is common practice as postfix needs to listen on system related ports which requires root. I thought that the master process is spawning sub processes if f.e. an email is sent which are running by postfix user. F.y.i. the postfix config was never touched (I just used plesk to...

Yes I think so: postfix 924 19080 0 12:21 ? 00:00:00 smtpd -n smtp -t inet -u -c -o stress= -s 2 postfix 925 19080 0 12:21 ? 00:00:00 proxymap -t unix -u postfix 4559 19080 0 12:17 ? 00:00:00 anvil -l -t unix -u -c postfix 8942 1 0 11:50 ? 00:00:00...

Thank you again for your help. One more thing: If I want to allow only postfix to send mails through port 25, can I specify a firewall rule? For iptables it would be something like: iptables -I OUTPUT -m owner ! --uid-owner postfix -m tcp -p tcp --dport 25 -j REJECT But I saw that many mails...

Thank you for your answer. Do you have tips how to do monitoring of mail traffic? I found Many email messages are sent from PHP scripts on a server. How to find domains on which these scripts are running if Postfix is used? but it seems that the logfile "mail.send" is not filled with data. I...

Thank you for your answer. I attached a log of running processes - I think nothing bad is running: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 273 0.0 0.0 0 0 ? S< Feb13 0:00 [raid5wq] root 312 0.0 0.0 0 0 ? S Feb13...

Hello, I recently got an abuse mail by my hosting provider, stating that my server is sending spam. The following excerpt was attached to the abuse mail: [ SpamCop V4.8.7 ] This message is brief for your comfort. Please use links below for details. Email from 94.130.34.42 / Sun, 18 Feb 2018...

Thank you for your reply. I was wondering if it is possible to change the hostname (with no negative side effects on PLESK) to "mydomain.com". So I do not expose my Plesk panel's domain "plesksub.mydomain.com" in my sent emails... I found how to do that in the manual: How to change or get a...
