Status: RESOLVED INVALID

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Dave Kimberley]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a

Compose message, click send, get the following message:

"Send Message Error

Sending of message failed.

The message could not be sent because connecting to SMTP server mailhost failed.
The server may be unavailable or is refusing SMTP connections. Please verify
your SMTP server setting is correct and try again, or else contact your network
administrator."

I have many mail accounts and all the ones that use port 25 fail to send
messages, my gmail account (port 587 and TLS) works.

This works on Mozilla Application Suite 1.7.11. I have tried using the same
profile and creating a new one but I cannot send messages with the Seamonkey
Alpha apart from using my gmail account.

Reproducible: Always

Steps to Reproduce:
1. Compose message, selecting account to send from
2. Click send


Actual Results:  
Get "Send Message Error"

Expected Results:  
Sent message

Which provider do you use? I remember some providers block outgoing connections
to port 25 (except for their own mailserver).

Pipex.

Mozilla 1.7.11 works on the same PC with the same mail accounts so it won't be
the provider.

Can you create a SMTP log as described under
http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#smtp ? Also try
creating a HTTP log as described under
http://www.mozilla.org/projects/netlib/http/http-debugging.html (you can skip
the nsHttp:5 part, i'm more interested in the
nsSocketTransport:5,nsHostResolver:5 part). Then zip those log files and attach
it here to the bug. Also try upgrading to a recent trunk nightly and see if the
problem still exists there.

Tried latest_trunk:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050918
SeaMonkey/1.1a

Still get same problem.

it looks like from the transport service log that we're connecting to the
server, but the server isn't ever sending us a greeting. This looks for all the
world like a virus checker or firewall or something intercepting the connection
on the port and not allowing data through. On your client machine, if you telnet
to port 25 on that host, do you get  greeting back?

Problem solved.

Already disabled windows firewall, Microsoft Antispyware.

Problem was a McAfee VirusScan Enterprise 8 setting:

Virus Scan Console
  Access Protection Properties
    Port Blocking
      Prevent mass mailing worms from sending mail

To solve select "Prevent mass mailing worms from sending mail" then click edit
button and add seamonkey.exe to list of excluded processes (mozilla was there by
default).

Maybe we should contact them to include SeaMonkey by default, let me see if i
can do something here (also i think this can be dangerous IMHO, does it allow
viruses/worms with the name mozilla.exe to send mail then? not sure if they do
the right thing here anyway ;)).
