any way to relay incoming email

[adison]

hi.
as said in a preevious post, i have no way to open port25 inbound because my IT department won't let me.
is there any possible way to relay this in stead?

[girish]

I will move this to Discuss since this is outside the scope of Cloudron at this point.

Maybe someone can recommend a 3rd party service. But if port 25 is closed, I am not sure how email can be relayed into Cloudron ?

better option is to relay out

[fbartels]

The "traditional" way to relay inbound mails is to have them delivered to a third party and then retrieve them via for example fetchmail or getmail. Fetchmail has an option called "multidrop" to deliver mails from a single pop3 mailbox into multiple target mailboxes.

Some years ago we had a prototype at work that would have been a hosted mail relay. A central server that accepts mails for licensed domains and then a small service on the customers system that establishes a websocket connecting to the central system and receive the actual mails through it (hence no need to open ports). Said connection would also have been used to relay outgoing mails. Sadly not enough commercial interest therefore it never left the prototype stage.

@fbartels so in other words, its not possible to do that on cloudron inbound mail?

[fbartels]

The traditional way would still work. You work probably has a google apps, microsoft 365 subscription, or maybe even a measly webspace where they currently do their mail. Do isps still give our mailboxes? And from there you just need to run fetchmail somewhere where it can reach your cloudron (for example on the cloudron server itself).

A quick google brought up https://github.com/jeboehm/docker-fetchmail/

Could do it with 2 cloudrons, having one handle email for the one that cannot.

[adison]

@robi but to be honest, cloudron should have something like this built in. to

[adison]

i ment @girish

@adison not sure what you are asking, are you asking to run email service on some other port? What should be built into cloudron? how would such a service work? if your IT won't let you open port 25, you cannot run an email service, there's nothing you can do.

[adison]

@girish what i'm asking for is for the relay or a relay option to be builtin to cloudron itself.

There are other threads on this topic on the forum already.

@adison A relay needs port 25, so it won't work for your case.

[adison]

@girish o. but can i still recieve emails inbound to the server? for example, wordpress wants to send emails, and its on the same server. cant it still do that?

[girish]

@adison sending is not a problem

[robi]

You can always receive locally from apps.
