My suggestion for a future version would then be: How about running dovecot-lda, if the user happens to be local, or a local alias? Or at least provide some sort of pattern matching: anything matching *@example.com , pass the message to

Why don't you configure all stuff internally and ask your provider to relay the e-mails from and to you via "smart relay"?? You will communicate only via smtp and only with your provider, and you can use a nice open-source bundle ( dovecot is mandatory because you wrote on that list :) ) in your LAN. > > > > > > > > > > ?

At one point seems like I found a write up in the Dovecot docs about having Dovecot directly listen on port 25 using Opportunistic TLS along with port 587 authentication, so only Dovecot was required to handle incoming email. Said another way, no requirement for Sendmail, or Postfix or EXIM. Just straight up Dovecot. If I'm remembering correctly, someone point me to the correct docs for

Hi all: I am evaluating mail server solutions for a small business. The trouble is, I am only a part-time admin and a newbie to mail servers. Most guides I have seen are rather unrealistic: they encourage you to expose your e-mail server to the Internet, and hope that you have the resources to keep it patched up. I would rather have an internal mail server that collects e-mails from a standard

I would be happy to take a pre-packaged mail server solution like iRedMail which includes RoundCube or whatever. I just need a "easy", practical guide to reconfigure it to 1) download e-mails from a multidrop, and 2) relay external e-mail to the ISP's SMTP server.

Actually, it is just a convenience/workaround feature, which comes handy only if your own MTA cannot handle dovecot's SASL authentication (must be something real strange) or there are some

Hi all: I am using the libvirt version that comes with Ubuntu 18.04.3 LTS. I have written a script that backs up my virtual machines every night. I want to limit the amount of memory that this backup operation consumes, mainly to prevent page cache thrashing. I have described the Linux page cache thrashing issue in detail here:

This does not seem a viable option then with Ubuntu 18.04. And changing XML on all guest VMs is extra work. Is there no other way? For example, are all such virtual machines not some daemon or systemd unit or set of units? Would it be feasible to

Hi all: I am using the libvirt version that comes with Ubuntu 18.04.3 LTS. I want to backup a virtual machine in a foolproof way: - Gracefully shutdown the VM. - Backup the disk image. - Restart the VM. I wrote the following script to do that: https://github.com/rdiez/Tools/blob/master/VirtualMachineManager/BackupVm.sh Writing that script was difficult enough because of the virsh limitations

Is it not possible to set up some internal SMTP server that only relies the e-mails to the external ISP SMTP server? The internal SMTP server would then act like a normal user's Thunderbird. At first I tought that the internal

Hi all: I have an Ubuntu 18.04 system. What is the easiest way to run all of my virtual machines with a low priority? Say a "nice" level of 15. I just do not want my virtual machines to have too much of an impact in any other processes on the system. Thanks in advance, rdiez

Hello everyone, it's my first post here on this mailing list and I hope, I make it right. I posted a question on https://serverfault.com/questions/1031441/dovecot-as-proxy-with-submission and nobody was able to answer it. So I decided to push that question here (I'm talking about any new dovecot version and I've tested it with 2.3.4.1 (f79e8e7e4)). I try to run a dovecot proxy

Hi all: I am new to e-mail servers and I am evaluating Dovecot. Not really the best combination. 8-) I am trying to find a balance between legal data retention requirements and online mailbox size. I do not want huge online mailboxes, as doing offline, rotating data backups could then take forever (among other reasons). I would rather avoid online (cloud) backups (data protection etc.). If I
