Topic: 7.5.1 External SMTP access problem

[Egate]

Hi guise

I have SME set up as dedicated server- client. Need wan access for office 2007 outlook. No problem wit POP3 but cant get smtp to authenticate. Searched forum extensively but cant get this resolved. Mabe somebody could help? Server wan ip is 41.134.162.165 Every thing was set up as suggested in forum.

This post http://forums.contribs.org/index.php/topic,37211.0.html is exactly my problem and my setup was done this way , but no joy.

Did this, yum update smeserver-qpsmtpd --enablerepo=smeupdates-testing and ran server update.

If i telnet to port 465 nothing much happens and if i use www.yougetsignal.com it shows pot 465 port is open.

Don't know if this might be a problem, but if i use www.mxtoolbox.com it reports that reverse dns does not match SMTP banner, don't think so though. SMTP i use is mail.maritzsiviel.co.za This is not the primary domain though.

Setup is like this. In more settings button-outgoing server i did click my outgoing server requiers authentication and also clicked use same settings as incoming. Also went to atvanced tab and changed SMTP server port to 465 and chose auto for incripted connection. Basicley gets a time out error if i run test.

Did try these setings.
# config setprop qpsmtpd TlsBeforeAuth 0
#  signal-event email-update

It can be changed back to the default by

# config setprop qpsmtpd TlsBeforeAuth 1
#  signal-event email-update

No luck

Webmail functions perfect in Explorer and Firefox. Any ideas or help would be apretiated.

Thought this might help. If i look at /var/log/sqpsmtpd/current  this is the last sessions log.

If i telnet to port 465 nothing much happens ...

This is what you should expect, since telnet does not perform an SSL handshake and set up an SSL/TLS authenticated/encrypted session.

Thanks for the reply Charlie. That would explain the telnet. Added as mush info as possible. Got it to work. First of, test account does not work from outlook and also i had to in the advanced tab set SMTP out going server to 465 and also Use the following encryption connection to SSL, does not work if set to auto. Domain rejected mail because it did not want to relay SMTP which it did not have to do, because it was meant for that server. Deleted domain and recreated. That resolved the problem. One more thing popped up however now. If i use outlook connecting from wan side it is possible to send mail forward and backward without a problem. If i make use of Fatcow, which is a online service provider a www is added along the line. For instance, if mail is mla@egate.co.za fatcow would reject mail because it does not have a user mla@www.egate.co.za  This is a bit worrying because there might be more servers experiencing the same problem. Any ideas would be appreciated.

test account does not work from outlook

Known bug with Outlook 2007 and 2010.
Just send a normal email to yourself as a test.

Looks like a setup issue with Fatcow, is it asking for an http account ?

Domain rejected mail because it did not want to relay SMTP which it did not have to do

You get this if you have your Outlook set up to talk directly to your ISP as an SMTP. You should be setting up Outlook to use you SME as the smtp server. Also, have you got the SMTP proxy status enabled in the Proxy settings of the Security section in the server-manager ?

Hi Axessit

Thanks for reply. With setup mentioned in previous mail, everything appears to be functioning if i send normal mail exept for fatcow, as mentioned. Fatcow is a email server that i have been using with outlook for a while.

Used to run a SME server at our location and is busy setting up one again, but things changed a bit. SMTP proxy is enabled. Was wondering if it could not have something to do with the problem, but could not rely see it causing problems from the wan side.

Thanks again for response.

If you have the smtp proxy enabled, then SME will intercept any mail (smtp) to the WAN and send it on behalf of your workstation, so that's why changing the settings in Outlook doesn't always fix things. You have ot have SME sending email properly first.

Glad things are working, just thought I'd also document this for other disciples of SME....

Hi Axxesit

I agree. This is why a posted what i found, might help somebody else having this problem. My smtp did work perfect from local network. Was just on wan side that i had a problem.
