Missing emails

[vodacom3g]

@v3g I am amazed that you sneaked in that "we seriously considering blocking port 25" and not a single comment from anyone! lol

Now just think you can do it and say well we did discuss it on the forum and no one objected! lol

We discussed it at length on the forum, in the blacklisting topics, so probably mosts of the regulars understand the reasoning. Also, the only reason is to stop spamming and blacklistings, so again everyone should see the logic in this. Port-shaping and blocking has been used by other network for financial reasons. That's obviously not the case here. Actually, think of it, we'll loose data revenue!

I've been very pro no blocking and/or shaping but in this case the blocking is to benefit all users unless you're a spammer. But we've not done it yet....

Now if someone could develop a virus attacking only spammers (as opposed to legit bulk mailers)....

@snap, the simplest solution might be to start using smtp.vodacom.co.za again - noting that a lot of changes have been made to improve the smtp service...

Another option would be to get a Gmail account and use their servers.

@syndre it only works if you use webmail as that is exactly the same as using my own smtp server.

Wouldn't it work if you use their smtp servers?

True, but I no longer use a desktop email client - for quite a while now, I have been doing all of my emailing directly from GMail's web interface - obviously setup with 20 odd business & personal "From addresses" for various domains - I used to use Mozilla's Thunderbird [with my GMail account], and IMO Thunderbird is an excellent piece of s/w compared to M$ Outkooked and M$ Outkooked Express, but I found myself drifting towards GMail's web interface in Firefox [of course] and further away from Thunderbird, until I eventually just didn't bother with Thunderbird anymore...

@ic actually a very good idea think I just have to get used to the idea that the emails will not be on my desktop or local server and believe that they will always be available.

One very big advantage is you have access to them no matter which system you are on and of course a local system crash doesn't touch you.

@syndyre you could use their smtp servers but then you would have the same problems of the originating ip being spam blocked.

I think ic's suggestion may just be the way to go.

I was a bit slow last night, sorry.

Just tried sending an email from the Gmail web interface and from Thunderbird to another address to check the difference in headers.

Both show the same originating IP:

X-Originating-IP: [66.249.92.170] - Gmail Server

The difference is here, Thunderbird:

from ?192.168.0.xxx? ( [41.243.xxx.xxx]) by mx.google.com with....

Gmail web:

by 10.70.113.16 with SMTP id...
by 10.70.70.15 with HTTP; Mon, 4 Dec 2006 21:37:50 -0800 (PST)

So the question is, which field do spam blockers check?
That's from an ADSL connection by the way so the IPs'll be different to Vodacom.

Both were also verified as being from gmail.com by DomainKeys:

http://antispam.yahoo.com/domainkeys

Not sure how many other ISPs/email providers use this though.

You could always download your emails via pop access even if you send them via the Gmail web interface.

@syndyre I actually dont how the spam blockers check. But as I said previously its weird that I can log on via the 3g card try to send the same email 10 times via the same smtp server and it vanishes every time. I resort to dial up and the email gets through every time. When I check the ip that I was given by vodacom which didnt work it is spam blocked in many places. I then log on using the 3g card again send the email and it goes through so it has something to do with the ip.

Yes I guess I could still keep a copy of all the sent and received emails. ic's way of doing things is sounding better and better!

The last relay|smtp server's IP address will be inspected for possible spam triggers, IOW the GMail Server as per your example, is the important one.

Yep, GMail offers flexibility and one can use either the web interface or something like Mozilla Thunderbird...

It works for me, but I tend to live a connected lifestyle where offline ways of doing things [like via an email client] have become alien to me - check the withdrawal symptoms when I cannot get connected .

I for one would be very dissapointed if I had to give up my personal SMTP. Having this gives me the freedom to move between networks seemlessly.

If I plug my laptop in at the office, at home, on the move ....... my mail works. All I need is a connection.

Would be serious pain in the butt having to change SMTP's all the time based on the network you use for connecting to the Internet.

Very sharp v3g - was trying to think of a suitable v... 3... g... reply but can't think of anything! lol

Blocking port 25 would have its advantages - like better control of (unintended and zombie generated) spam from the VC network.

But I'm in the process of setting up a access controlled (username/password) SMTP server for our business on the outside to enable the people having to change SMTP settings in their mail clients if they move around.

If port 25 is blocked, it would kill this function as well.

I don't think we'd be adverse to opening up port 25 to users who sign an AUP.

As stated before, there is no intent other than stopping SPAM.

Could this work for you?
