9. Problems

Check that your POP client is configured with your username @dslr.net. POP3 servers can use just a simple "username" or "username@domain.com" format for the login name, and our servers require the latter.


POP Username: joeuser@dslr.net
POP Password:


POP Username: joeuser
POP Password:

If the name you tried to use belongs to another DSLR/BBR user, you will not be allowed to use it. All user names are reserved for their use, whether they participate in the DSLR Mail system or not.

I'm using OE. I set up the account following the instructions in this FAQ. I can receive email with no problem, but I can't send.

In my Outlook Express settings, my ISP account is set as the default. I even deleted it, but still couldn't send using DSLR email.


You will have to use your ISP for SMTP mail. You can still use your DSLR email address even though you are using your ISP's email server.

In the box for POP settings, enter mail.dslr.net and in the box for SMTP settings enter mindspring.com (or whatever your ISP is).

There have been several reports of password problems when initializing a new account ...

Take care to enter your password correctly! The password IS case-sensitive!

Rejected Passwords - Make sure that the USER NAME you use is the one for your PRIMARY account and not an alias account.

Your password at DSLR is limited to 12 characters only ... characters beyond that are ignored. For the POP server, just enter the first 12 characters of it, or change to a 12 character password on DSLR.

If you are using a firewall, you may have to open ports 995 (SSL) or 1100 to successfully access your mail.

If you find that you can receive email, but cannot send, try entering the SMTP server address for your ISP mail account as opposed to "mail.dslr.net." For instance, "smtp1.sympatico.ca". (This is an example only. Your SMTP entry will be different.)

It would appear that with some ISPs, you are unable to access the SMTP server "mail.dslr.net" and have to use your ISP's SMTP server to send mail.

In other words, if you are unable to send email using the settings provided, try plugging in the SMTP server address you normally would use for your ISP email account.


Feedback received on this FAQ entry:
  • Is there a different setup (different settings / port) for outgoing Emails; than using Ports 25 or 26 -or- using my home ISP's SMTP server? I don't want to setup my DSLR emails to use my ISP's SMTP server for outgoing (sending) email. Reason is my DSL ISP has had problems and DSLR's email system has been my backup resource. Also I sometimes Email when traveling, which means a different ISP.

If you edit your Blacklist or other setting, and you find that it doesn't "take", try going to the "edit" function in the mail control panel. Don't make any changes, just hit edit, and it should cause your changes to take effect.

You will not be able to access the DSLR Mail Forum until you have created your first mailbox (alias).

I just spent the last 1/2 hour trying to figure out why I couldn't receive my pop3 mail, checking and rechecking the settings, spelling etc. I kept getting the "can't find server" error. Then I remembered my NIS/Outlook firewall rules which I set up to block those HTML bugs. I added a rule to "allow mail.dslr.net" and it's working fine now.
Thanks to rcdiver for posting this in the forum.

The message could not be sent because one of the recipients was rejected by the server. 
The rejected e-mail address was 'xxx@xxx.com'.
Subject 'Re: xxxx, xxxx, Account: 'mail.dslr.net',
Server: 'mail.dslr.net', Protocol: SMTP, Server Response: '504 :
Sender address rejected: need fully-qualified address',
Port: 25, Secure(SSL): No, Server Error: 504, Error Number: 0x800CCC79

This occurs if you have not entered a full email address in your e-mail client's account settings.

In the e-mail box you must have a qualified e-mail address formatted like the one in the graphic: user@domain.com

In an effort to help protect customers against unwanted junk e-mail (spam), some providers institute "Port 25 filtering."

If your provider does this (Bellsouth and Earthlink, for instance) you will not be able to send e-mail without making some adjustments.

In your e-mail software, (Outlook, Outlook Express, etc.) please change your outgoing (SMTP) mail server for all secondary accounts as instructed here: /faq/6039

This will have no impact on how your sent mail appears or on the ability of people to reply to you at your secondary email account.

Note: Another method of dealing with this is now available. DSLR Mail now also listens on Port 26, so you can try putting that into your email program setup screen and see if you can send via that port.

You can read an informative explanation on why ISPs block port 25 in this thread:

Feedback received on this FAQ entry:
  • you should use port 587 instead of 26. 587 is the standard "submission" port.

You came here probably after seeing a mail of yours TO someone@dslr.net being rejected with a message like this:

Greylisted for 300 seconds (see ...)

The mail server generating this error message is using a system called Greylisting to filter spam and viruses. It relies on Mail Servers behaving according to the standards and usually doesn't require any action by the user. Your mails should only possibly be delayed.

Who to contact in case of problems

If you wish to have your domain whitelisted because your mail server does not quite follow mail RFC standards, please post in our site help forum
