Hello I am using for 2 years now a account with unlimited domain names with 2000Mb space and 30 gigs bandwidth.
But I have big problems with the outgoing mail sending (SMPT) The owner of this company, a very nice guy, can't solve this problem.
So all my customers are having from time to time problems too. Not all the time and even when they can't send they can receive.
So who knows a good hosting company with a GOOD server and support staff?
Please let me know ASAP and thanks in advance!
Peter

Just curious, what kind of SMTP problems are you having? Because some ISPs are blocking port 25 now.

this the trouble, the company owner tell me its my mistake, but all of my clients are having this from time to time.
Its about port 25 also. I have checked all settings over here even shutdown my antvirus soft but no help..

No email's are being sent out at all..?

No for over 2 days now!
Message:
An unknown error has occurred. Subject 'test', Account: '***@k***.org', Server: 'mail.****.org', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B
This all accounts on this server, my other emails are going just fine on another server.

Are your other mail accounts through your ISP, or are they through another hosting company or 3rd party email server?

It sounds like this could be the problem:

CAUSE
This problem occurs when your mail server requires both Secure Sockets Layer security (SSL) and Secure Password Authentication (SPA).

No I am not using office only outlook express, and again my mail is sending without any problems on other servers.

[Are your other mail accounts through your ISP, or are they through another hosting company or 3rd party email server?]
Yes all mail in trouble are on the same ISP

Be sure that you have secure connections turned on for Outbound SMTP and that your account username is using an @ instead of a +.

There seems to be quite a bit of information regarding this error, it all points to a misconfiguration in your client software, not on the server.

Try searching google and read through some of the results, you should be able to find your answer there. Here is how I searched:

Yes I know, but again I did not solve this problems also my clients are having this problem from mail browsers from outlook express to opera.
Time to time everything is working fine but again some days not.
So if the problem is in the software from my side, tell me why is it working from time to time, this also with my clients?
I still have guess that my ISP is blocking my IP, I toold him so so I also opened up a DynIP for all my clients, 24 at present time. Still it did not help..

So I am talking at the time with some hosting companies as my dedicated server in the Netherlands has no more space, we have over 5000 visiters there (messageboard with over 30,000 members)
But also this is working on Appache as wel and no trouble there in outgoing mail..

I don't understand what you mean by this. When you say "in trouble", does this mean that these are not working? Or do you mean that the working emails are all from your ISP.

If you mean that all your mail accounts that are working come from your ISP, then you problem may (99%) be due to the ISP blocking port 25. If this is the case, no matter which hosting provider you switch to, if they don't have alternate SMTP ports, you won't be able to send mail.

If it's the ISP that's blocking port 25, a quick fix for your current host and email would be to just set the SMTP servers on all the email accounts that aren't working to your ISP's SMTP server (this is outgoing servers only, the incoming POP servers will stay the same).

All emails send trough my provider are not working from time to time.
But I have another provider too; those emails can be send trough this server without problems.

But coming back to the server I am hosting 24 domains for clients:
This is going on for more than 15 months now, not all the time, one time I can send and again another day I can't.
Yesterday I was not able to send trough makser, my reseller account there, so I changed the sending part to @extremejourney.com which is at the same server using the same IP as makserver, and it went out.
Today all smpt on all accounts here are blocked on this server.
So for outgoing I have to use my own server in the Netherlands or to use hotmail>

To all giving me the ideas for the solution thanks!
It has been port 25 on the ISP. They opened another port for me and the problem is gone!
Again my GREAT thanks to all who tried to help me!
You are GREAT!

Can I remove the account...?

I have a same problem with one of my clients he use a ComCast as his ISP.
When he sends direct email with outlook he gets same error massage, but when he use a proxy server there is no problem.
