Postby guigsilva » Fri Jun 18, 2010 6:32 am

Hello everybody,

We have a problem here, one of our users are trying to send an mail and the RCTP down´t receive. Zimbra send a msg to my user with:

Protocol error: host xxxx.xxxxxx.xx[ip.ip.ip.ip] said:

250 RCPT TO accepted (in reply to DATA command)
I can see in /var/log/zimbra.log

I try to send mail from other account in zimbra to other account in destination server but I get the same error...
From gmail I can send to zimbra and to destination mail without problems.
I google it and find that some exchange servers have problems with ESMTP protocol greeting.
Any one have this (command line too long) error ????


Thanks in advace
Guilherme

You will need to ask the Admin of the remote server why they believe the line is too long; as they should be able to review their log files.

Thanks for the help,
On the other side the admin says that the server shows the message as Non Delivery. I will ask for more detailed log and post here.
Thanks again

Hello Everybody!
The problem was solved.
We have a inspection rule on Cisco router to the traffic on port 25 (this apparently has a know bug...) shuting down this rule and forcing the postfix to greeting with HELO insted EHLO solved the question...
I will try to reactivate the EHLO greeting with the inspection rule down to see if works.


Thanks again
Guilherme
