SMTP error Net::SMTP: Unexpected EOF on command channel

[Aldin Music]

Hi Support,

I am having an issue trying to use the SMTP option with bugzilla, after configuring all the needed settings for SMTP I get the following error Traceback:
at Bugzilla/Mailer.pm line 174
Bugzilla::Mailer::MessageToMTA(...) called at Bugzilla/Token.pm line 76
Bugzilla::Token::issue_new_user_account_token(...) called at Bugzilla/User.pm line 2039
Bugzilla::User::check_and_send_account_creation_confirmation(...) called at /var/www/html/bugzilla/createaccount.cgi line 37

With the following error in apache log:
Net::SMTP: Unexpected EOF on command channel at lib/Email/Send/SMTP.pm line 74

Thanks

Sounds like a network problem to me, you should have a look on the
logs of your mail server.

Mit freundlichen Grüßen,

Then I would suggest to have a look at AppArmor/SELinux, although the
only thing I know of is sendmail, which isn't used in your case. But
maybe there's more or some other kind of packet filter interfering with
httpd and SMTP communication. Besides that, you may try to configure
sendmail in Bugzilla, remember AppArmor/SELinux in that case, and see
if this works like telnet does. If it does, this could mean it's
something security relevant with httpd and SMTP communication.

[Aldin Music]

Hi Thorsten,

I am using CentOS 6.4 x64, and I have disabled SELinux completely. I have tested sendmail, and I was able to use bugzilla and create a new account. I have received that the new account has been created and needs to be verified, but trying with smtp I don't get that far. I am un clear what security would cause something like this. This is what my logs are showing me, but it looks like the communication goes through and the account gets authenticated. Then it just disconnects.

Is this the same FROM you successfully used with telnet? Can you
repeat the commands in your log with telnet and see what happens?
Except STARTTLS, but this shouldn't make any difference.

[Aldin Music]

Hi Thorsten,

Correct it's the same from address. This address is created on the third party; smtp provider's control panel. I have just repeated the steps and I was able to send the email just fine to a Hotmail account and internally also.

Connected to third party smtp address.
Escape character is '^]'.
