Sending mails to internal user ober external mail server

Post by itksystemhaus » 2019-03-20 18:08

Hello,

we have installed hMailserver onto our server, because we have a software which needs imap access but can't use complex passwords. Our provider wants complex passwords.
So the main reason for installing hMailserver was to get the emails via POP3 and to store them locally for the software. As additional benefit we also have implemented imap access in all outlook clients and send also emails over the hMailserver, which sends the emails over our provider's mailserver which is used as relay.
So this works fine for us. But the problem is: every user has a mobile phone and connects directly to the provider's mailserver, so that they have email-access everywhere. Also no problem, it works.

Our problem now is, that internal emails from one user to another are routed directly to the other users mailbox, so he can see it in the outlook client and our software also has access to this email. But when the user is not in the office and only has access with the mobile phone, he will not see this email on the phone.

Is there a possibility, so send all emails, also internal mails over the relay server ? Or is there any other solution?
We do not want to expose the hMailserver's ports to the internet, because the passwords are to weak.

Thank you in advance.

The other solution is to expose the hMailserver's IMAP ports to the internet and have the smart phones connect to your hmailserver for IMAP only

Exposing just the IMAP port is less risky, but is still risky.
What can be obtained by hacking an IMAP password? They can't send mail with just IMAP
At worst they could access (and delete) mail that is already received...
Just 'cause I link to a page and say little else doesn't mean I am not being nice.
