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):

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

Problem started this morning.

    Hello Benny,

    Any word on solutions as i have a few dozen emails that need to be sent.

    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.

    That worked, not sure how my SMTP port changed but now there is new issue.

    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?

    Yes, they are all correct and yet all the accounts are not working. I have tried changing the username with and without @etc.com

    no joy...

    these problems all started yesterday morning, odd thing was that one or two emails send after i changed the port back to its correct setting but then these messages started.

    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.

    Using macbookpro. not using gmail account, using bluehost provider.

    all other clients are working. "internet and phone"

    what's the manual way?

    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, in the end found out the reason was bluehost has blacklisted my IP for some unknown reason. Since then, now whitelisted.

    • State changed from “new” to “resolved”

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