535 Invalid credential

[manmln]

Hello,
I installed Postal using instructions and try to test sending emails.
Opened telnet
type EHLO command - get 250-My capabilities are
250 AUTH CRAM-MD5 PLAIN LOGIN
type AUTH LOGIN command- get 334 VXNlcm5hbWU6
type username copied from Sending E-mails page - get 334 UGFzc3dvcmQ6
type password copied from Sending E-mails page - get 535 Invalid credential

No matter what else I do (created new key, tried base64 encryption) I get invalid credential.
Please advise,
Michael

Both auth plain and auth login need base64 so its hard to test manually as its very easy to encode some extra whitespace at the end of the value being encoded.

You may get on better with a real mail software library, or even a desktop client will be able to send the message, just not receive one.

I tried entering both encrypted and unencrypted username/password in Mautic - get connection timeout.
I also tried to encrypt using 2 different tools and get the same string.
My username was generated as mr/myregistry-info. Are there any illegal characters?
