Emails via SMTP relay divert to queue

Post by JRH » Fri Dec 07, 2007 6:37 pm

Hello all,

Long time since I've been here! All has been working fine for several months up until now...

I have a bizarre problem that's probably easily solved:

17:31:37.502 [5420] <SMTP> Client connected from 149.254.192.***
17:31:37.502 [5420] <SMTP> 220 Quick 'n Easy Mail Server
17:31:37.721 [5420] <SMTP> EHLO Calculon
17:31:37.736 [5420] <SMTP> 250-Supported extensions:
250-AUTH PLAIN LOGIN
250-VRFY
250 OK
17:31:37.986 [5420] <SMTP> AUTH LOGIN
17:31:37.986 [5420] <SMTP> 334 VXNlcm5hbWU6
17:31:38.205 [5420] <SMTP> AMFTZXM=

17:31:38.471 [5420] <SMTP> ADA4ODKZNTIXMQ==
17:31:38.471 [5420] <SMTP> 235 Authentication successful.
17:31:38.752 [5420] <SMTP> MAIL FROM: <jrh@fake123.net>
17:31:38.752 [5420] <SMTP> 250 OK
17:31:39.002 [5420] <SMTP> RCPT TO: <james.hamilton@****.com>

17:31:40.096 [4612] <SMTP> Incoming message: 828D55916A7B427D9D03DBE01A272D5F.eml
17:31:40.096 [4612] <SMTP> Copying message to: c:\Mailboxes\queue\
17:31:40.096 [5420] <SMTP> 250 OK: Queued as: 828D55916A7B427D9D03DBE01A272D5F
17:31:40.345 [5420] <SMTP> QUIT
17:31:40.345 [5420] <SMTP> 221 Bye
17:31:40.345 [5420] <SMTP> Client disconnected from 149.254.192.***

For some reason, instead of relaying onto the remote mail server, it's storing all mails sent via SMTP in the \queue.

The DNS is definitely correct (I've tested it in the configuration, and it always comes back with the MX record).

Nothing's changed, as far as I know.

Does anyone have any ideas on what's wrong? :)

Are you areu you didn;y change anything to your computer configuration?
Maybe a firewall change/update?
Maybe your ISP blocks outgoing SMTP traffic sinc recently?

Nope, I definitely didn't change the configuration. Definitely no firewall change. I'm fairly sure the ISP isn't blocking, but I did realise that most of the emails in the queue before mine were ones that had happened during what I've now found to be a massive breach of security that I've now plugged from a .com.tw address using the relay to send out thousands of emails.

Has that caused the problem? Will my ISP's DNS server now block all emails?

Problem solved - there were 31,000 emails in the queue, all not sent by my users or me...
