Re: Serious iPhone SMTP Issues - cannot send

Thanks for the reply. I should have come back in and posted that we had resolved this. We were a bit too aggressive in blocking at the HELO level (SMTP | Properties | Security tab} and blocked what appeared to be 100% spam coming from: [*.*.*.*] It turns out that some smartphones use the bracketed I...

Re: Fighting Hackers

Why not just block YLMF-PC at the HELO block?

SMTP Properties
Security TAB
Configure Blocks (at the bottom).

No need to block IP addresses if the HELO is blocked.

Re: EHLO Blocking - HELO *.*

Update on this thread: it would appear that smartphones are sending their HELO in this format EHLO+[10.0.0.121] The Android that I tested used the above. I assume iPhone do the same. The IP is the one assigned to the device by the WiFi connection from the DHCP on the internal network. Definitely rec...

Re: EHLO blocking - extension

Yes it would appear that smartphones are sending their HELO in this format
EHLO+[10.0.0.121]

The Android that I tested used the above.
The IP is the one assigned to the device by the WiFi connection from the DHCP on the internal network.

Definitely remove the [*.*.*.*] from the block list.

Abuse Detection and Prevention

I read somewhere recently that we should NOT have BOTH Connection Dropping and Abuse Detection and Prevention "on" at the same time.

If this is true then my suggestion is to have a text warning next to both these options in the backend to alert people.

Re: Fighting Hackers

I read somewhere recently that you should NOT have BOTH Connection Dropping and Abuse Detection and Prevention on at the same time. Perhaps someone from ME can confirm this? When I read this I wondered why ME does not have a text warning next to both these options in the backend to alert people. We ...

Re: EHLO blocking - extension

Hello Brett, Yes the function is working in 9.54. I have found a minor bug and have already reported it. Basically if you have *.br blocked and the HELO name is static.bringit.br it doesn't get stopped. Apparently the code checks the first .br finds .bringit and then lets it pass. The function in SM...

Re: EHLO Blocking - HELO *.*

Hello again, Yes we see a lot of email come in with this bracket format - [192.168.1.100] the IP addresses are all different of course. Here are a few examples from the log files: EHLO EHLO+[197.157.18.98] EHLO EHLO+[185.99.32.109] EHLO EHLO+[10.75.60.50] After careful review of these messages it ap...

Serious iPhone SMTP Issues - cannot send

We are getting calls from iPhone users who are unable to send email from their devices. It would appear new iPhones (and perhaps a recent update) has changed the way their SMTP settings are configured on the phone. I read that it automatically uses the format username@hostname instead of username@do...

Re: EHLO Blocking - HELO *.*

Not quite sure what you mean by HELO *.* - Are you actually seeing the asterisks? You certainly do not want to block *.* as I am pretty sure that will block everything. You should update to 9.54 (or above) as it has the full working function for the HELO process. Here is what we are using in there t...

Re: URL Blacklisting configuration

Just to clarify for others who may be wasting a lot of time (as we did) trying to get this to work: Capture-SMTP-DNS-BL.JPG The top section DNS Blacklisting IS working. DNS Blacklisting is to identify known spammers within the selected lists by IP address. The bottom section URL Blacklisting IS NOT ...

Re: EHLO blocking - extension

Thanks for the heads up about this.

This looks to be for IP addresses? Yes?
[*.*.*.*]

What about *.stream and the others I mentioned?
