Hello

Are you guys updating the postfix release anytime  soon?

I ask this because i cannot use office 365 as a relay server with this.... unless i have a postfix  2.9 and the lastest firmware of airwaves got 2.6.6.

 

Anyways i was trying to relay it because our IPS got banned on the Spam house, i mean all the range... a /17 which belong to the service provider... and well  i though well i will just relay it on my office365 and it just didnt work... then i saw this document...

 

Here is the source

Hi Carlos,

 

Can you provide a bit more detail about the problem?  Is it that emails generated by Airwave are failing to be delivered because your entire IP space, including the public-facing AMP IP, are listed at spamhaus?  What is/are the recipient domain(s), and relevantly are they under the control of you or someone friendly?  For example could the recipients whitelist your IP block to bypass DNSBL checks?

Hello Spencer

This is just a demo airwaves i use to show clients what they can do with airwaves but anyways

 

Just look at the logs down at the end of the post, you will see that spamhouse is telilng me that my ip which is that one you see thats the ip of my firewall is being blocked

Now  if i go to spamhouse it does tell me yes its being block so i cannot use the embebed mail server of the airwaves... neither i can relay with my office 365 because is not compatible with the version of the airwaves postfix.

I also got a ticket Case #1418888: so you can get further information of the case(well if you got access to that which i dont know)

 

May 13 16:37:05 airwaves postfix/smtp[39905]: 09FA51E05C6: to=<test@airwave.com>, relay=mx01.arubanetworks.com[199.127.104.59]:25, delay=0.81, delays=0.11/0/0.44/0.26, dsn=5.0.0, status=bounced (host mx01.arubanetworks.com[199.127.104.59] said: 554 Service unavailable; Client host [airwaves.alternetworks.local] blocked by zen.spamhaus.org; http://www.spamhaus.org/query/bl?ip=190.141.109.242 (in reply to RCPT TO command))

Re: AirWave 7.7 beta is available

If you only want to send test mails to @airwave.com or @arubanetworks.com addresses then we could ask IT to whitelist your IP address.

 

2nd possibility, in addition to AMP Setup > General > Additional AMP Services > Use Embedded Mail Server > yes, below that do you have a Mail Relay Server configured?  Your ISP likely has one you can use that may not require client auth to send email.

 

(What is the feature in postfix 2.9 that is not in 2.6 that would solve the issue?)

Re: AirWave 7.7 beta is available

Im really not sure about that...

But that is what microsoft says on their KB

For now im asking our ISP to help us to unblack list our ip address with spamhouse...

Re: AirWave 7.7 beta is available

If you are behind a dynamic IP address, spamhaus is not going to remove that address from the PBL, since that is more or less the purpose of that flavor of blacklist.

 

I still believe the best solution would be to ask your ISP if they have an outbound mail server for their customers to use, and then configuring that as the mail relay server in the AMP setup page per my previous message.  (If *that* outbound mailserver requires client auth, then you may be out of luck as far as Airwave messages go.)

 

Upgrading postfix will not, by itself, solve any client auth issues, because Airwave currently does not produce postfix config files that use outbound client auth.

 

EDIT: let me amend that slightly -- when I wrote the above paragraph I was thinking we overwrote main.cf every time you save the AMP Setup/General page, but in fact we use postconf to modify it.  So it is possible you could hand-edit main.cf to use outbound client auth and Airwave would not disturb those settings in the course of normal operation.

Re: AirWave 7.7 beta is available

Well i could as my service provider to do that...

 

But its supposed that we got an ip range not by DHCP we got a static ip addresses  a /28

 

And about that i was overwritting the main.cf editing the file... with winSCP to configure the relay.

Ah, I apologize for my wrong assumption :-)  I believe in that case it should be possible to have your subset of addresses removed from the PBL, although it may take a while.  In the meantime an internal relay is probably the best workaround -- good luck!
