ISPConfig e-mail problems

[mr_bo]

Hi,

Can someone please help.

I have a new install of ispc on Ubuntu and all works well except for receiving mail. I have configured outlook express and read up loads on here and the net but still scratching my head.
I can send/receive ok in oe with no errors and send mail ok but cannot receive mail.

Thanks in advance.

Which errors appear in the mail log when you send a email to your account?

[mr_bo]

I'm looking at /var/log/mail.log and this is what I see after I hit send/receive in oe:

time=0
Sep 29 19:27:42 server pop3d: Connection, ip=[::ffff:192.168.0.1]
Sep 29 19:27:42 server pop3d: LOGIN, user=web1_admin, ip=[::ffff:192.168.0.1], port=[4126]
Sep 29 19:27:42 server pop3d: LOGOUT, user=web1_admin, ip=[::ffff:192.168.0.1], port=[4126], top=0, retr=0, rcvd=12, sent=39, time=0


and this is from when I tried to send a mail to my work address:


Sep 29 09:47:21 server postfix/smtp[14904]: BA416E2382: host mail-xxx.xxxxx.com[xxx.xxx.xxx.xxx] refused to talk to me: 554 mail-xxx.xxxx.com
Sep 29 09:47:21 server postfix/smtp[14904]: BA416E2382: host mail-xxx.xxxx.com[xxx.xxx.xxx.xxx] refused to talk to me: 554 mail-xxx.xxxx.com
Sep 29 09:47:21 server postfix/smtp[14904]: BA416E2382: to=<xxx@xxx.co.uk>, relay=mail-xxx.xxxx.com[xxx.xxx.xxx.xxx]:25, delay=2.1, delays=0.1/0.04/2/0, dsn=4.0.0, status=deferred (host mail-xxx.xxxx.com[xxx.xxx.xxx.xxx] refused to talk to me: 554 mail-xxx.xxxx.com)

(had to edit ip's and server)

Do you run your server on a dsl or kable line with a dynamic IP address?

[mr_bo]

Yes, it is currently on dsl with dynamic ip, for the next six weeks. Then I will be changing service provider to a static ip dsl service.

Ok, then you're most likely blacklisted. You can check that on http://mxtoolbox.com/blacklists.aspx

[mr_bo]

Ta for that, will check it out when i get home.

If so, can I be removed?


Here is the results:

Most likely the receiving SMTP server runs some sort of RBL checks and perhaps another on known dialup lines. If so, even unlisting your ip wouldn't change much, as your IP can be traced down to be a dialup one and will sometimes be blocked.
I don't think you will be able to "unlist" the ip as you'll get another one after a reconnect with your ISP and the play starts again.

You can relay through another mail server: http://www.howtoforge.com/postfix_relaying_through_another_mailserver

Thanks for all your help.

I already pay a company to host my sites for me and I wanted to get away and host myself, but my current isp is obviously the problem, so I have shifted everything back to the hosting company for now as in 2 weeks I will obtain my mac code and move to a better isp with a static ip service that does not block port 25 and then shift everything back to my linux box here. :)

[mr_bo]

Hello again, I'm back..

I have now switched to an isp with static ip and all is ok on that side.

But now I can send mails ok using outlook express, but get
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

xxxx@xxxxxxx.co.uk
No Such User Here

when I send a mail to the account on isp config.

Thanks for any help in advance.

[falko]

Is xxxx@xxxxxxx.co.uk listed in /etc/postfix/virtusertable?

[mr_bo]

Is xxxx@xxxxxxx.co.uk listed in /etc/postfix/virtusertable?

Yes it is in there.

[falko]

Is it exaclty xxxx@xxxxxxx.co.uk, or maybe something slightly different like xxxx@www.xxxxxxx.co.uk?

[mr_bo]

Is it exaclty xxxx@xxxxxxx.co.uk, or maybe something slightly different like xxxx@www.xxxxxxx.co.uk?

It is exact, and to be sure I also added it manually.

If I send a mail from a web based e-mail, google, the mail delivers ok and drops into my inbox on outlook express, but if I use another mail account which is on the server I am currently renting then it gets sent back with the error.

[falko]

Can you check if the MX record for xxxxxxx.co.uk is correct?
dig mx xxxxxxx.co.uk

I have an A record for mail.xxxxxx.co.uk and all mails seem to be getting through except from the server I rent.

I will be giving up that server when I get this sorted and moving everything to my ispc server.

I think it is safe to do so tonight and take a gamble as I think the ispc server is ok.

[mr_bo]

Hi, the ispc server has been up and running for a little over a week with no mail problems.
Thanks for your help, I have learnt alot from here. :)
