Hi Jeroen
I know about the sad Port-25 story, but that does not seem the point hier.
Thought so, but always something to keep in the back of our minds.
The cases look like this:
user@DomainHostedAtMhs is sending a mail to our mhs mail relays to normaluser@bluewin.ch. This works as expected.
Our mailserver then forwards the mail to the MX hosts for @bluewin.ch domain. This works too, (no reject on smtp level) but the mail never appears in the inbox at normaluser@bluewin.ch OR it appears, but without attachments.
Our sending ip at mhs is 213.188.32.73.
The only thing I can think of is a mailcorruption on the mailplatform of bluewin in that case; especially when you get no errors back from their SMTP server. Only people who will be able to debug this thus is the Bluewin folks, I hope they have a disk-space full warning on their platform and are able to properly check where things go wrong....
Only thing that comes to my mind now is: are you reading the bluewin account with their webif or over POP3/IMAP/whatever?
Might be that a certain MIME structure is not properly parsed in the cases that there are missing attachments. Of course the mails which go missing altogether indicate a bigger issue at hand, seems Swisscom is having quite some issues lately... (3G down, etc)
