Hi all,

I know this might be not the right place to post this issue as it is more related to Elastix than iRedmail but am trying to get any help.

there is an option in elastix to use remote smtp for sending voicemails

am trying to use iRedmail as the smtp but I keep getting error : Authenticate not accepted from server

though am using TLS and port: 587 , it working with hotmail , yahoo and gmail it just doesn't work with my iRedmail.

Elastix use postfix for sending the mails and here is the main.cf setup for it:

virtual_transport = lmtp:unix:/var/lib/imap/socket/lmtp
relayhost = mydomain:587
smtp_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_tls_auth_only = yes
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 2
smtpd_tls_received_header = yes
