Failed to send message

Reported by Ian Baines | May 5th, 2016 @ 05:16 AM

MAILMATE Version 1.9.4 (5234)

Not sure what is going on, but the program is not allowing me to send any emails. I receive an error message for all my accounts:


Failed to send message

Unexpected return code 0 (expected 220):
“K [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready.”.

Tip: Open the Activity Viewer (⌥⌘0) before retrying. The SMTP log file might provide additional information.


Problem started this morning.

    Based on the error message it looks like MailMate is connecting to an IMAP server instead of an SMTP server. Try reviewing your account settings and make sure the SMTP setting are correct -- including the port number if you use an explicit one.

    This is a different problem and it's an IMAP server (rejecting your credentials). Are you sure the username and password is correct for this account?

    The messages sent were probably those related to the Gmail account. It's hard to debug the password-related issues since the error message simply tells us that the server rejects the username/password.

    You can try another email client to see if the same settings work there. Alternatively, if you know how to use a Terminal window then I can tell you how to try to connect and authenticate manually.

    Sorry about the late reply (it's kind of a Holiday in Denmark).

    I wrote Gmail, because your initial issue appeared to be a Gmail account.

    I checked Bluehost and it seems their IMAP settings depend on some box number: https://my.bluehost.com/cgi/help/37

    Connecting manually would be something like this:

    telnet box100.bluehost.com 143
    ...
    0 LOGIN user@example.com password
    

    This is then without SSL. With SSL it would be something like this:

    openssl s_client -crlf -connect box100.bluehost.com:993
    ...
    0 LOGIN user@example.com password
    

    Let me know whether or not authenticating works in the cases above. Using the same settings as you do in MailMate.

    Thanks for the update. It's a bit troubling that they don't know why they blacklist an IP...
