After the Migration, Powweb is Deleteing Attachments. We are not Geting Any type of Allert that the Email was deleted. note: the Attachements Are Faves in the form of an EXE file. I sent the Files Out fine before the migration. Now they ARe being Deleted without Notification Or Confirmation.. Has anyone Else had this problem, And Do Anyone know how to Remedy this problem. Tech Support Claims That There is no Way to let An exe File Through POWWEB servers, But we proved that Wrong on the phone using the Web based Email. I suggested it had something to do with their SPAM filterring... Anyway Anyone Got ANy Suggestions.. I'm Using Outlook Express. And I really Can Afford to Turn Spam filterring off on the Other Clients Domains..

It was difficult to read your posting with your use of upper case letters mixed in everywhere.
Change the .exe to something else before attaching - such as ._xe and the filters probably won't pick it up. Then all you have to do once they're received is to change the extension back.
Endurance have multiple levels of filters that the old Powweb didn't. We're simply learning what they are and what restrictions are now imposed. One way is better for some, this way is better for others.

I just tried sending an .EXE attachment from my PowWeb email address (using my mail client, not webmail) to my personal email address at comcast.net. Thunderbird 1.5.0.4 failed to send it with the message:
An error occurred while sending mail. The mail server responded: Blacklisted file extension detected. Please check the message and try again.
The mail server gives this response after the mail client finishes sending the message. The exact response from the server is:
550 Blacklisted file extension detected
I then renamed the file from "TEST.EXE" to "TEST.EXE.2" and it sent successfully. I then retrieved the message in my comcast.net mailbox, renamed the file back to "TEST.EXE", and tried to send it back to my PowWeb email address. I immediately got this non-delivery notice:
A message (from <xxxxxxxx@comcast.net>) was received at 29 Jun 2006 9:01:01 +0000.

Endurance have multiple levels of filters that the old Powweb didn't. We're simply learning what they are and what restrictions are now imposed. One way is better for some, this way is better for others.
The problem I have with that is, we shouldn't have to learn what the restrictions are. We should be told up front what the restrictions are so that we know how to do things properly in the first place.
I don't fully understand, but does that mean that your account is now internally blacklisted?

It's just the file extension (.EXE) that's blacklisted. It's just that Endurance is blacklisting/filtering email in both directions, incoming and outgoing.
Of course, I think a better way to fight spam would be to stop allowing users to spoof the "From" header, but that's just me :)

Actually, I could convert the File to a PDF file and send it.. I'm concerned more about POWWEB deleting emails from my CLIENTS and not letting anyone no their emails were deleted. First, this had been going on for about a week and I though the email was sent. I've called, and talked to techs for hours, each time getting different excuses. Even though I explained CLEARLY, That I can send the file using MY EARTHLINK account. They would try to insist it's not a POWWEB issue. I didn't get any notification that POWWEB had delete my emails (I think they may have fixed this notification now). The Average users Don't even now what an extension or Zipped file is. So try To Get Both Ends the Change the Extension then Change it Back would be a disaster. After (7) days, I could have mailed the invoices if delivery was the issue. I'm more Concerend about all the Problems since the Migration. One Tech said we could stay on the Old Legagcy System, But It's been Bought Out by Some Other Company,and we we be serviced by them, Yesterday, The Tech said we Don't have a choice. Which is it..
Back to The Questions at Hand. Is there anyway to control the emails / attachment being Deleted Without turning off Spam Filter completely?? Worst Now, After Yesterday Tech Screwwing with My Account, I can't Send Email from that user Account.. Further Down Hill
Oh, And I wonder If POWWEB uses word Filters to Delete Emails Also. is ti possible thet it could find a mark word and delete your emails?
Thanks

If an email contains these file extensions, they will not be allowed. Here is the KB article: blacklisted file extensions (http://www.powweb.com/knowledgebase/read_article.bml?kbid=1193)
These files are often used in spam/malware mails and a number of email servers block these (I believe Gmail blocks exe).
It's not necessary that these files are attached, sometimes they can be embedded into the email message (like .pif, .scr, .url).
Even if exe is renamed as _exe, it contains the word exe and I guess the filter is set for filenme.*exe* and it might be rejected/bounced. Probably we may need to rename the extension to something else and indicate a note on the email message about that or simply zip the file and send or upload the file into website and give the URL in the email.
We have the same filter at work. The workaround mentioned above works fine for all blacklisted exentions.
Just add a line to the email you send telling customers it's a security measure for their protection. It'll give them the warm and fuzzies.

Note that the workaround is to replace the first (or last) letter of the extension, not to simply add an underscore as in ther example Govi quoted.
.exe becomes ._xe or .ex_ and so on for other extensions.
As Doc says, tell them it's for their own protection as well.

I searched the knowledge base and couldn't find it (other than clicking on the link you provided). How did you find it?!? Also, forgive me for sounding stupid, but how can a .PIF or .SCR file be embedded into the email message? I don't think I've ever seen that before.

There is no way you can control the deletion of the blacklisted extensions. Period. Turning off spam filtering will not change that, because it is technically not part of the spam filtering, it is part of the SMTP server. As such, it will always be active for both incoming and outgoing mail, no matter what you set in your account (and I bet you believed Endurance when they said you would have control over the filtering).
Hey cc1030, you are a sharp person!
In the PHPMailer fix I posted I requested a new forum topic be started to explain how to create emails that won't be secretely deleted without warning. This file attachment issue is very much on-topic.
My PHPMailer generated SMTP email had attachment, and included image in html part of multipart mail. The outgoing (outside SMTP server) email was deleted while the 2nd email going to an account on internal (same Server) was allowed to pass throug. This cost me a tremendous amount of time and effort to learn what is stated above .... WE SHOULD BE TOLD EXACTLY WHAT THE SITUATION WILL BE ON NEW PLATFORM BEFORE ... AND POWWEB SHOULD NOT GO INTO HIDING FOR OVER A WEEK WHEN THE PROBLEM ARISES. Where's the information????????? Again, this is why America is full of great legal expertise. Because companies do this and then get sued, class action style, for a boat load of money! The cover up is worse then the error.
Perhaps someone who knows spamassasin (when of those spammers in our Endurance community) can tell us all (we the normal business people) how to create emails that dont' get deleted. THIS IS POWWEB RESPONSIBILITY, and they should be held financially responsible for their incompetence as relates to customer lost business, lost time, professional imbarrasment. That's why they have insurance, to compensate customers who loose money from their *deliberate* "woops forgot to mention" mistakes.

Most of my clients are not very computer Literate. They would be just using a program like Quickbooks or some accounting program to send a Invoice by email. Like a fax by email. The Faxing program do all the converting. Again most wouldn't even know what an extension is. and becaue it's using the Print function and not the SAVE function, I would doubt if the file would even be saved locally.. ...
Why would the Web Mail client let you attach an [EXE] file, then automatically delete it after you send the mail?
Thanks
