my outgoing mail is limited to 2 megabytes, 10 mbyts incoming?

By edems ·
For 2 months now, I've been unable to forward large messages, over 2 megabytes, even though I can receive mesgs up to 10 mbytes. The problem occurs only with email clients. Webmail, works fine. Outlook Express and Thunderbird both halt part way through the upload. Both complain that the SMTP server quit. I tried a different account, borrowing one from a friend, and that didn't help. I have a Motorola cable modem with Cox cable, a WRT54G Cisco router, and 3 computers (2 on Ethernet, and one wireless tablet). All 3 are affected. I have tried one computer without the router, and that didn't work. I tried booting with Linux Knoppix (with the router), and that didn't work (that is, Thunderbird with Knoppix failed. So, it isn't a windows problem). I even reloaded Windows XP on one machine. The only thing that I haven't tried eliminating is the modem. The modem doesn't show any errors, and neither does the router. Cox support hasn't been helpful. At one point, on representative told me to contact Microsoft. I hate to buy another modem, but its the only item, other than Cox cable, that hasn't been eliminated as a problem. Anyone have any ideas on this?

Cox

by Churdoo In reply to my outgoing mail is limit ...

It sounds like Cox is limiting the SMTP message size from their cable internet clients. This would cause the symptoms that you're describing, and would NOT necessarly affect the webmail client.

Receiving emails could easily be different criteria (10MB vs. 2MB) as receiving and sending are done through entirely different mechanisms (typically POP3 vs. SMTP).

So I daresay, if you replace your cable modem, you'll only find the same symptoms.

The Cox support rep that told you to contact MS, should simply be fired. The rest should probably also be fired if they couldn't even figure out that you were asking about their SMTP policies.

The cable and DSL providers have been clamping down on SMTP policies more and more; initially it was to help combat spam, but recently I think it more has to do with lowering their support costs -- they want to make using email clients a pain in the a$$ so you use their webmail -- so they can hire the schmucks that can't think for themselves, don't need to learn about the myriad of email clients, can only answer questions from a script, and can't even spell SMTP.

SMTP mail problems

by edems In reply to Cox

The error I get is:"Sending of message failed. Teh message could not be sent because connecting to SMTP server smtp.central.cox.net failed. The server may be unavailable or is refusing SMTP connections. Please verify your SMTP server is correct and try again, or else contact your network administrator.", with Firebird. With Outlook Express, I get the following error message:Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Subject 'test with large file', Account: 'pop.central.cox.net', Server: 'smtp.central.cox.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F.

I think the error message that I would get if the file exceeded the SMTP limit would be different.
The error above is described as:
0x800CCC0F: Connection closed
This error means that your modem or network was disconnected. If you access the Internet through a dial-up connection, there may be noise on your phone line and you may need updated modem drivers, or an init string. With other Internet connections, the problem may be with your network hardware or drivers.
(http://pcperformancetools.com/outlook-express-errors.htm).

This description indicates the signal is dropped. And it is dropped before the end of the message occurs. I checked the outlook smtp.log file, and on normal transmissions, the end of the message is signaled with a "." on a line by itself. On failed messages, it just the log lines just stop before that happens.
I contacted Cox Saturday, and that guy said he would put in an IT problem report. He said they would get back to me, but it would be more than one day. Haven't heard yet.

Odd problem.

Give me an S

by Churdoo In reply to SMTP mail problems

The S in SMTP stands for Simple, i.e. Simple Mail Transfer Protocol. Its error messages sometimes leave something to be desired. If you're saying that all outbound messages over 2MB get cut off, but messages under 2MB go through, then appropriate error message or not, it's likely a server-side size limitation.
The fact that the Cox support dude wasn't on the clue train, frankly is no surprise either; we all have our horror stories about tier 1 support.
Did you look at their email policies? Did you try adding authentication to your SMTP settings in your email clients? If not, that may make a difference.
Good Luck!

SMTP Files size solved

by edems In reply to Give me an S

Hi, thank for your help. Cox let me down there. Using the Exclusionary principal, I replaced the modem. For reasons I don't understand, that solved the problem.
