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
dropletB.domain.com -> domainB1.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.
