    what is the MTA you are using? I'm assuming you want to transfer the mailfolders of your users to your newly setup mail-server. Squirrel mail is just the web interface for your user to access their stored mailbox.



    To assist you with this we need to know the MTA (ie, QMAIL, postfix etc) and the flavor of linux you are using.

The solution i will be posting assumes you already have postfix installed in the new machine and that your new postfix server is able to relay mails. Old configurations has been copied/transported to the new server ( and the only remaining task is to move all the mails to the new postfix server.

copy /home (your maildir) to your new server - check your postfix configuration to verify your maildir

also make sure you have copied

/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow
/var/spool/mail

to your new mail server ( these are your mail related files)

Note: This is assuming you have identical setup you have with your old email server. double check your postfix configuaration before proceeding.

Good Luck

Why can I not send my e-mail. This is causing problems.


There are many many reasons for not to be able to send email.
In order to narrow down cause of problem, you need to provide more info (or organize info for yourself to do trouble shoot).
If it's web mail (hotmail, gmail,yahoo mail etc) or POP mail (Internet provider's email, company mail or even your own domain's mail etc)

also depend on which mailer (mailing program) you are using (MS outlook, Windows Live mail, or access from browser etc)

Sometimes, problem is not your side but server side, if so there is nothing you can do.

If you can give us more detail, someone (include me) can help.
don't give us your mail account info, but what kind of email (web or POP), what program you are using (how do you read and send email).
is there any error message returned or it was sent but never reached to destination ?

How to Setup Linux Mail Server


<p><span>Email is an important part of any Web site that you create.

In RedHat Linux we use sendmail to create a mail server that will relay your mail to a remote user's mailbox or incoming mail to a local mail box. On our RedHat we will find sendmail's configuration file as /etc/sendmail.cf. If you download and compile sendmail you would find it in /etc/mail/sendmail.cf. To configure sendmail you have basically 2 options. Either you edit the sendmail.cf file directly or you create the sendmail.cf from an m4 file such as sendmail.mc.

After installation of sendmail package it locates as sendmail.mc in /etc/mail. In the sendmail.mc file I have find the line DAEMON_OPTION and edit it with # before the line to uncheck it. Then I find Local Domain and edit it also with the system FQDN. After editing save the sendmail.mc file. After exiting from sendmail.mc I moved this .mc file to sendmail.cf with m4. Here the SendMail configuration is complete. Then I go to the /etc/dovecot.conf file and edit it. I just find the protocol line and uncheck this line. After that I save this .conf file. After all configurations I have start the service demons with chkconfig command and restart the both services. And the mail server was going on swiftly.</SPAN><br> <p><span><span> </SPAN>So it is very easiest job to configure a mail server in RedHat Linux enterprise server.</SPAN>

E-mail comes in all right, but I get the error message when I try to send messages out. . . says server won't accept my address


Some ISPs will block your ability to send mail via SMTP client on your machine. If the email server is different from the one offered by your ISP.

the typical port for the SMTP service is TCP port 25. To allow your outgoing email to route past your ISP, change this to TCP port 587.

On Linux and Mac OS/X, this is found in file /etc/services
On Windows XP, try 'windows\system32\drivers\etc\services'

Locate a line such as
smtp 25/tcp mail

and change it to
smtp 587/tcp mail # port for outgoing mail

I cannot send mail on my MacBook Pro (Intel) using OS X's Mail program at home using my 2wire; it works at the office on Cable. What's wrong with my settings and is it software or hardware?


You may be using the wrong SMTP address for the Outgoing mail server address for your email service.

If you are not sure what your SMTP Outgoing Mail Server address is, then you can reference this link
below, to locate the Outgoing mail server address of your current email service provider

Link: POP & SMTP Email Server Addresses
---------------------------------------------------------------------
In regards to checking your mail settings in Mac OS X Mail you will need to perform these few steps:

*Launch Mail
• Click on Mail name and select Preferences from
the drop down menu.
• Now select the Account tab.
• Locate your affected email account from the side
bar and from Account Information, make sure
your Outgoing mail server address is correct.

I am using a .Mac account as an example,
but the same principal applies.

Now if you do find that the Outgoing mail server address for your email service is correct, then the issue may be with the SMTP server for your email service.

One way to determine SMTP functionality however, is to go online and use the web mail page for your email account and send out a test email.
---------------------------------------------------------------------
I would also recommend you make sure your Macbook Pro also has the most current version update.

Apple usually has bug fixes in each of their version updates for the Mac OS X Mail application, as well as other built in Mac OS X applications.

If you are still unable to send outgoing mail, contact your service provider to get more assistance and have them check your SMTP server address, authentication and connection with their Outgoing Mail servers.

Composing and attaching files


Dear friend, At first you should find the source of problem, Yahoo server? Browser? or maybe your OS?!
To find that you should go step by step from low steps to high steps, I mean first check your browser, then OS and if they're good it belongs to Yahoo server.
So at first check by other browsers like IE, Safari, Firefox,Opera and.... Note: Empty cach before testing. If they couldn't help you, Re-install your default browser, or check the last or previous version of your browser.
The second way is to check your mail by other computers, use other computers (in coffee net or your friend's pc), check if it belongs to OS or no, check mail on other OS like WIN, MAC, LINUX If this could help you, it means that you should repair your OS, for example you should re-install it. Note: Check did you install any software that my conflict with your browser? if you install any new program, remove them temporary and check again.
I hope it fix.
NOTE: I suggest you check these ways on clasic mode of yahoo mail.
Good luck
