Hello, 2 days ago, my recipients suddenly stopped receiving emails. Now as further investigation I found out, that everything is fine until I insert attachment (in this case a jpg file). Is someone else experiencing this type of problem?

Thanks,

I guess your server spam filter is the problem here. I recommend you to read the following page.

It happened again. I dont understand what spam filter are you meaning of? My ISP or the SMTP I use cause I dont see the mails in the spam folder on my Google mail.

Thanks,

Have you read the page I sent you the link of? It is all explained on it.

Read it till the bottom and the link for anti-spam suggestions but, still cant solve/pass by the problem. It looks like my ISP, or the SMTP service is memorizing my message. When I try to send the same message using different SMTP it still don't get received.
Its frustrating that I cant find the logic, that is what pisses me off!

ps: The message is not going to SPAM at all...it just don't get anywhere.

Yes, I understand your problem and absolutely all I know about this problem is in the page I sent you the link of. I wrote that page myself with all the information I have. Try to start another message starting from very simple sentences and try.

Hey stanbusk,
I already tried and every time I change significant portion of the mail it goes through... if I delete a sentence or paragraph. When I try the same message again I have the problem...

Again, after some time even the new message get lost again and there is no chance to see when that happens (except from the bounces and errors). So I'm trying to see the logic, where is the glitch... who is filtering that so I can find workaround.

Thanks,
S@

Yes, this sometimes can be a nightmare. There is a word, several words, a sentence, an expression, some punctuation or a link that causes the problem. It is hard to find out because your server doesn't tell you where the problem is. You are a client of that server but they threat you like an enemy. Could you attach your document here, I could try my server and I will get a report.

Not Nightmare... Inferno! ... Diablo 3 way of speaking
Anyway, thanks for the help,
here is the doc. If you find any suspicious thing, please write back.

Right now I'm trying a workaround. Make 3 similar mails and split the list in three. Then we will see how it goes.

Thanks,
S@

(It's UTF-8 so you probably wont understand anything)

Have you tried to remove the very last explanation mark?

No I haven't... I did the full re-designing of the mail but left the ! at the end. So far so good...
