ISP account anyone?

Postby Max Headroom » Sat, 28 Jun 2014 10:57 am

Can I ask if any of your legitimate emails sent ever get bounced back due to the sender server IP being "blacklisted"?

For the record, I'm referring to legitimate emails, personal or business emails, that are sent singly, i.e. not bulk emails or anything of that nature.

I get this too frequently to ignore and I've discussed it with my ISP Support, but I can't say that things are improving.

Input welcome.

Thanks.

A number of smaller companies in SG use singnet accounts... so I'd guess that the singnet domain (or the IP of the mail server) got blacklisted. It happens if a lot of SPAM emails come from a single domain.

Not sure why you are using singnet for major personal or business email ;)

Yes, I, too, think that. But it's the ISP's job to prevent spam mail from being sent from their IP blocks, for instance by setting a FUP limit for their subscribers on outgoing emails. I assumed this was standard practice amongst ISP's actually. I mean, to get blacklisted, you really need to send a lot of spam for a longer period of time.

Well, most of our mail is sent through our own SMTP, but every now and then, I prefer not using our main TLD email addresses to protect them from falling prey to spammers.

Wondering if anyone else here has this bounce issue.

not with Singnet but when I was with another ISP we used to have this kind of issues ...

whenever a customer notifies us, we switch the outgoing SMTP and amend the reverse entries accordingly ... we clear this within a day ...

with Singnet I doubt they do it ... as any change process has lot of approvals and road blocks ... plus Singnet infra is pretty much outsourced internally

good luck getting it fixed

use Gmail or the likes instead of Singnet says me ;)

PS.its not hard to get into spam lists ... not gonna get into details but few spam DBs mark even single entry as spam ... and leave the onus on the ISP/IP owner to remove themselves .... false positives galore ...

guilty unless proven innocent ...

Thanks ecureilx.

In all fairness, they've been working on it and keeping in touch with me regularly to keep me in the loop. But, bottom line, it's not getting better.

Worse, I wouldn't be surprised if for every bounce alert I get, there are at least a few where the receiving server just deletes my message without delivering it and without bothering to send a bounce notification.

It never happened with my ISP in Europe and I think it was because they're quite tough on accounts that sent bulk email.

Let's see how it goes in the next few weeks.

As I said, Singnet is too big to make changes like that on the fly ..

A lot of SMTP servers now don't bounce, as bounces can make the bouncing server get blacklisted ..
