The firewall is set to ONLY allow traffic from the reverse proxy. Sounds to me that the reverse proxy settings are pointing to the old server and you don't have it set for the new server. Can someone please clarify this for me? Thanks! ![]() Since we have a separation of duties I cannot check or change any firewall settings and I want to make sure that we exhaust whatever options that we can before I request opening ports on the firewall. I was under this impression by the consultant that was hired to help with these migrations. This makes sense in that the new server is not externally accessible, but I thought that the reverse proxy was supposed to keep things syncing through the public address from the old server. As soon as I go to cellular I cannot connect again. Since we are in testing I found that I had to first install the self signed SSL certificate on the iPhone and I can then connect to the mailbox on the new server as long as I am on my corporate WiFi network. Is there a way to pass the initial log in through so the user doesn't have to log in twice.įor ActiveSync, we have a fleet of deployed iPhones that my test account recognized that the mail server had changed and updated the server accordingly but broke with an unable to connect to server message. With OWA, I'm finding that when I authenticate to the old server it recognizes that the mailbox is on the new server and redirects the user to click the link to the new OWA and prompts to log in again. According to the documentation unbound uses the port range 1024-65535 for outgoing requests.I am in the testing phase of migrating from Outlook 2010 to 2016 to be able to upgrade to 2019 and have a couple of questions about ActiveSync and OWA's ability to reverse proxy connections after the mailboxes have been migrated to the new servers. Port 53 unimportant for the firewall configuration in this case. Important for Hetzner firewalls ¶įor all who are struggling with the Hetzner firewall: Please use HTTP_PORT=1234 and HTTP_BIND=1.2.3.4 instead. Important: You cannot use IP:PORT bindings in HTTP_PORT and HTTPS_PORT. To bind a service to an IP address, you can prepend the IP like this: SMTP_PORT=1.2.3.4:25 If you have a firewall in front of mailcow, please make sure that these ports are open for incoming connections: Service You may also adjust mailcows ports via the nf configuration file. If this command returns any results please remove or stop the application running on that port. See this () or this (unrouted.io) guide for information about how to use iptables-persistent with the DOCKER-USER chain.Īs mailcow runs dockerized, INPUT rules have no effect on restricting access to mailcow. You should disable it (if possible) and move your ruleset to the DOCKER-USER chain, which is not cleared by a Docker service restart, instead. There are several problems with running mailcow on a firewalld/ufw enabled system. The following table contains all operating systems officially supported and tested by us ( as of June 2023): OS However, in some cases there may be incompatibilities between the operating systems and the mailcow components.

RAM usage examples ¶Ī company with 15 phones (EAS enabled) and about 50 concurrent IMAP connections should plan 16 GiB RAM.Ħ GiB RAM + 1 GiB swap are fine for most private installations while 8 GiB RAM are recommended for ~5 to 10 users. A default configuration spawns 20 workers. The more ActiveSync connections you plan to use, the more RAM you will need. mailcow comes with a webserver, webmailer, ActiveSync (MS), antivirus, antispam, indexing (Solr), document scanner (Oletools), SQL (MariaDB), Cache (Redis), MDA, MTA, various web services etc.Ī single SOGo worker can acquire ~350 MiB RAM before it gets purged. mailcow is a full-grown and ready-to-use groupware with many extras making life easier. We are aware that a pure MTA can run on 128 MiB RAM.
