custom SMTP per user and same domain

[rosch]

Hi there,

what I'm asking is similar to maxxer's thread from 2016 Use custom SMTP per user.
Unfortunately there was no posted solution.

I'm looking to configure the external sending where each user has his own smpt account at the same mail relay mail.relay.com.

I followed the zimbra wiki Relay per Domain, version 8.8.10.

Files and desired content:

Code: Select all

/opt/zimbra/common/conf/bysender

user1@domain.com [mail.relay.com]:submission
user2@domain.com [mail.relay.com]:submission

Code: Select all

/opt/zimbra/common/conf/relaypasswords

[mail.relay.com]:submission user1:password1
[mail.relay.com]:submission user2:password2

Is this even possible?

I know it's been a while, but yes, this did the trick, thanks.

ps: I didn't have to

Code: Select all

zmcontrol restart

after every update of the relay_password file.

Code: Select all

postmap /opt/zimbra/conf/relay_password

is sufficient.
