EmailSend - Line too long
07/30/12 6:40 AM

hi all,

i am still struggling with the EmailSend function using an
CR1000@OS25.
i have mentioned the same error in this post:
http://www.campbellsci.com/forum/messages.cfm?threadid=5BBF3176-E4A0-688A-BF34C14972DC52FB

I get the error-message "Line too long" when trying to send mails with attachments via 1und1.de(Nemesis ESMTP) (relative big provider in germany).
As a german guy i really need to be able to use this provider, as a lot of customers are using this service and hence want to get their mails at least CC'ed to this provider.
I am able to send mails via googlemail or gmx.net, so i suspect the mail-server at 1und1 is a little "pedantic".

So i set up a "hMailserver" (with a vanilla-config) on my machine to get some logs, which showed the same line-to-long error.

So i must suspect there is a little "incompatibility" between the loggers output and the expected input at the server side at least for this mail-server when it comes to the transmission of the attachment (something like a CR->CRLF->CRCRLF issue?)

I have no in-depth knowledge of email, so maybe i am completely wrong, but it would be nice if someone could confirm that there is a problem with some mail-servers.

hi,

the file i am sending for testing purpose, is a
Ascii-TOA5-dat-file (downloaded via Loggernet from logger and then uploaded via FileControl to the USR-drive).
The filesize is ~70kB (315 lines).
The longest line is the second headerline (fieldnames/channelnames) which is 859bytes+CRLF.

greetings

Can you confirm what you have in the from field in email send as we think the problem may be in the length of the message ID field the logger constructs, which includes the from address.

hi,

my from_field consists of one email-address.
it is declared like this :

Const EMAIL_FROM="abcdefgh@123456789.de"

the length of this address is the same as the original used in the program.

This has been identified as an issue with the email code in the datalogger (as well as RTMC -- they use the same code). The lines are not being restricted to 76 characters. Many email servers will tolerate these longer lines, but some will not.

This will be fixed in the next OS of the datalogger, and also the next release of RTMC (neither has a scheduled release date at this time).

I apologize for this inconvenience.

hi dana,

this is good news.
Thanks for pinpointing the reason for my problems so quick.
I will wait for the next OS-release (and in the meantime try to use another mail-server)
