STMP mail error

(1/3) > >>

mattrick00:
When I attempt to do a mailing and I send a test email (step 4 of 5), I get this error:
"Sorry. A non-recoverable error has occurred. Invalid response code received from SMTP (outbound mail) server while attempting to send email. This is often caused by a misconfiguration in the CiviCRM Outbound Email settings. Please verify the settings at Administer CiviCRM >> Global Settings >> Outbound Email (SMTP)."

However, when I check my SMTP settings (administer/Configure/Global Settings/Settings-Outbound Mail) by clicking on the "Save and Send Test Email" button, it works fine. I see "Your SMTP settings are correct. A test email has been sent to your email address," and then if I check the email it was sent to, I do indeed receive the email. Why am I having trouble with mailings?

All help appreciated!

I would suggest you ask your host to tell you what response code is being sent from the SMTP server.

Ok, spent a bunch of time with Bluehost tech support, and they tell me that, as is evidenced by the fact that I can send out a test email through the Administer>>Configure>>Global Settings>>Outbound Email screen, that the problem is not with Bluehost (my hosting service), but with CiviCRM.

Why would it work when I send a test email through the Global Settings>>Outbound Email screen, but not when I try to send a test email in the Mailings>>New Mailing>>Test(step 4 of 5) screen? Isn't it using the same SMTP info?

Still confused...

The big different is the from/reply-to headers we set when sending a civimail. I suspect bluehost is rejecting those email because of that

Ok, just talked with Bluehost again. Apparently, even though I have entered a valid email address, password, SMTP server, and SMTP Port in both Joomla and CiviCRM (hence, why it works when I send a test email), the Bluehost tech looked up the error message generated when I try to send a test mailing in CiviMail and it fails--and to Bluehost, it looks like the email is coming from a completely different username.

I have setup info@communitybikeproject.org [nofollow] as the FROM email address, yet Bluehost sees the email as from b.79.3142.33725ac05f6ba4c8@communitybikeproject.org [nofollow]. Since that is not a valid username, Bluehost is rejecting the email.

Why is CiviCRM generating this username when I send out a test mailing, and how do I fix this?

Thanks much for all the help so far.
