Mailman 3 hosting
Is it possible to configure Mailman 3 for an already registered domain?
You can also set up separately - a mail domain (e.g. "example.com"), and a web UI domain (e.g. "lists.example.com").
Please note, that for a second-level mail domain (like "example.com") it wouldn't be possible to use a mail server along with Mailman 3, as they will share the same MX record. However, it's possible to configure email redirects for addresses like "email@example.com", which don't belong to Mailman 3. Hence, email, which is not related to the mailing lists system, will be forwarded to an external mailbox.
Do you offer mailboxes?
No, we don't.
What methods are used to ensure the proper delivery of email to our subscribers? DKIM, SPF support?
We maintain our own carefully groomed mail relay with a dedicated servers farm for the best Yahoo deliverability.
SPF and DKIM are supported indeed.
Why emails from a mailing list fall into Spam folder of my mailbox?
Unfortunately, even with the most rigorous configuration of MTA (Mail Transport Agent), some ESPs (Email Service Providers) still consider mailing lists as suspicious correspondence. The only reliable way to solve this is with help of SRS (Sender Rewriting Scheme). Follow this screenshot to set up DMARC mitigation, which enables SRS for your mailing list.
Are there any limits in sending messages? Any other limits?
No limits. But we monitor our senders' activity and will flag in case of mass complaints.
Are we running on a shared host? Where is it located?
Yes. The server is located in the EU.
Portability of our data? Will we be able to obtain a backup of our list data and server files?
Definitely. We provide a PostgreSQL database backup as well as lists archives in mbox files.
Do you support custom integrations with Mailman 3 API?
Yes, we do. The feature is disabled by default, reach to the support if you need it.
