Hi Guys !
I have server with VestaCP but I want use one mailbox on office365.
In vesta I add mailbox with forward to office365 personA@example.com > personA@internal.office365.domain.com
Now I get email in office365 and this is work but problem is in send to other domain on server with vesta (example2.com) or the same domain (example.com)
If i try send to other domain (example2.com) on this server I get return message :
550 5.0.350 Remote server returned an error -> 550 smtp auth requried
And in vesta I see:
2017-08-22 13:22:43 SSL_write: (from mail-eopbgr20074.outbound.protection.outlook.com (EUR02-VE1-obe.outbound.protection.outlook.com) [184.108.40.206]) syscall: Connection reset by peer
2017-08-22 13:25:22 dovecot_login authenticator failed for (127.0.0.1) [220.127.116.11]: 535 Incorrect authentication data
2017-08-22 13:30:22 SMTP command timeout on connection from (127.0.0.1) [18.104.22.168]
What can I do to make this configuration work?
id some of you try to combine veste and office365 with one domain ?
