Hi,
I’m trying to add email account to my Outlook.
Unfortunately, I got this error:
Mar 6 10:24:46 localhost postfix/smtpd[3164402]: connect from unknown[45.xxx.xx.xx]
Mar 6 10:24:46 localhost postfix/smtpd[3164402]: warning: unknown[45.xxx.xx.xx]: SASL LOGIN authentication failed: Invalid authentication mechanism
Mar 6 10:24:46 localhost postfix/smtpd[3164402]: disconnect from unknown[45.xxx.xx.xx] ehlo=1 auth=0/1 quit=1 commands=2/3
I’ve tried to use different Encryption methods:
- None
- SSL/TLS
- STARTTLS
- Auto
Unfortunately, no luck… 
Did someone had the same/similar problem?
Thank you!

Hi @shoaibkk,
Thank you for your time!
Both 143, 993 for IMAP
Also both 587, 465 for SMTP
Of course, everything is forwarded and open!
P.S, On phone I’m using a TypeApp application and I can connect my emails. Only problems with Outlook 
Thank you!

Hi @shoaibkk ,
Done, ticket has been created.
Thank you!
Sorry, but can you tell me OS of your server and do you use mac, linux or windows from where you connect using outlook ?
FYI, I just checked from my mac that it worked, you can see my Outlook version as well.
I even sent an email and it also went through.
Just checked on Windows (Outlook 2016) worked.
