Question

postfix headaches - send mails between different droplets, same hostname.

Hi, i’ve a problem with postfix sending mail between virtual domains in droplets. I’ve 2 droplets with several domains in each droplet with virtualmin: dropletA.domain.com -> domainA1.com -> domainA2.com
dropletB.domain.com -> domainB1.com -> domainB2.com

when i try to send mails between my domains there’s a problem… perhaps postfix try to send locally?¿: Sending from domainA1 to domainB1: SASL authentication failed; server <dropletB.domain.com> said: 535 5.7.8 Error: authentication failed: authentication failure

If I send to any external domain (gmail, hotmail, …) no problem.

Thanks!

Hello, First of all we can’t help you out easily when you don’t provide any information about your server. Once you ask a question, we need to know where we are dealing with to help you out. So what kind of server are you running, what configurations are you using? Atleast post the main.cf. Did you check your logs for any more information?
