Last week we set up a Postal server for DNForum.com - migrated the forum (est in 2001 with over 1/2mil users) to a new server, moved all dns to CLoudflare and went for our own SMTP server.
Many of you will say: this is overkill! And, it might be
Server specs:
Company: OVH // DC: London
CPU: Intel Xeon-E 2136 - 6c/12t - 3.3 GHz/4.5 GHz
RAM: 64 GB ECC 2666 MHz
Data disks: 2×4 TB HDD SATA
The setup process is laid out here (could be useful for some): https://maria.zone/tutorials/set-up-new-postal-open-source-mail-server-v-3-x/
The task for us is to send email out to all our users and actually see: how really many active email addresses we have. .. again, the forum has been up since 2001.
We can't really use any 3rd party SMTP service as the bounce rate wll be high, and the service will be suspended barrelly started.
The processors and RAM are on 99% vacation
Disk space seems to be more than fine as well.
-------
Next, setting up another Postal > in this case >> on a VPS
Let us see how far we get with these specs:
CPUs: 4 (E5v4 CPU)
RAM: 8GB (swap = 4GB)
HDD: 60GB
Location: UK
This Postal server is also for a 20-years old forum acorndomains.co.uk, only in this case we have 15.5k members. Currently we are using PostmarkApp for sending out system emails > a test of sending a newsletter end by the 15-20% bounce-rate and the fun stops.
.. email channel is the only gateway to our users, so we have decided to control this passage ourselves.
