When my internal postfix MTA send a NDN 501 syntax error - line too long it send it with null from (from<>). Next, this message is send to the 501 syntax error ftp external postfix MTA to send it to the Internet. The problem is that this message is bounced with the following line: said: 501 syntax error in parameters or arguments (in reply to mail from command)) 501 Syntax error: Empty email address. (in reply to MAIL FROM command)). What can I do? Thanking in advance. Best regards. Rolando.

You can http://postfix.1071664.n5.nabble.com/501-Syntax-error-Empty-email-address-td80189.html report the complete log entry that contains that message without removing any leading or trailing content. And also say which machine logged that message (the original client or the relay). In all probability the message was rejected by a misconfigured external system, so the only thing you can do is try to talk some sense into the operators of that system, or accept the fact that bounces back to said system will be undeliverable. -- Viktor.

Fist of all, this is the arquitecture. mta3: frontend MTA that relay incoming messages from Internet to my company. mta1: internal MTA that is owner of my domain (domain.com). This MTA recives incoming message from Internet through mta3 and send messages to Internet through mta4 mta4: This MTA send messages to Internet. Let's say that is an incoming message from [hidden email] to [hidden email]. The account [hidden email] is over quota and bounce the message. Here are the logs of the three MTA's. ----------------------------------------------------------------------- mta3 recives an incoming message from Internet and send it to mta1.

Perhaps you have invalid "extra" email address fields set for the admin copies? Or, if you turn off all your switches to send copies to yourself, does the problem disappear? What pattern have you seen with the cases which have allegedly failed? Does the customer actually receive the email? What's showing in the email archive? (assuming you've turned it on and installed the addon to allow you to view it) Which emails *are* sent vs *not*? What addons do you have insta

[SMTP Error] 501 Syntax: helo needs hostname (V 5.3.2) Quote Postby LesD » 2012-12-21 15:43 I have an issue since upgrading ASSP to the latest version. I have been on the ASSP forum but need some help here.ASSP is now generating hundreds of rejections with the message: [SMTP Error] 501 Syntax: helo needs hostnameI actually got some complaints that valid mail was being rejected (gmail?).In ASSP there is a section for validating HELO but that is all turned off.The feedback from the ASSP forum has been that it is actually a valid message meaning that someone is connecting with a blank hostname and it is actually hMS that is doing the rejection.The problem is that I am not seeing the rejection in the hMS log even though I have Application/SMTP/TCP-IP/Debug ticked for hMS logging.My sample log entries are:hMS log shows just:"DEBUG" 1520 "2012-12-17 00:05:00.103" "Creating session 20437""SMTPD" 1520 20437 "2012-12-17 00:05:00.103" "10.27.27.35" "SENT: 220 DesserGroup.com""DEBUG" 1520 "2012-12-17 00:05:00.213" "Ending session 20437"while ASSP log showsDec-17-12 00:05:00 Connected: 173.9.62.249:1664 -> 10.27.27.35:25 (listenPort) -> 10.27.27.35:4128 > 10.27.27.35:125;Dec-17-12 00:05:00 173.9.62.249 [SMTP Error] 501 Syntax: helo needs hostname;Dec-17-12 00:05:00 173.9.62.249 disconnected (0 seconds);My sample was countered with a different hMS log sample"SMTPD" 4388 5 "2012-12-21 08:02:47.157" "10.69.5.95" "RECEIVED: ehlo""SMTPD" 4388 5 "2012-12-21 08:02:47.376" "10.69.5.95" "SENT: 501 EHLO Invalid domain address.""SMTPD" 4388 5 "2012-12-21 08:02:53.939" "10.69.5.95" "RECEIVED: QUIT""SMTPD" 4388 5 "2012-12-21 08:02:54.173" "10.69.5.95" "SENT: 221 goodbye"Why am I not seeing these log entries in my log?My reaction is that this is in fact an error generated by ASSP but I just want to check here.
