hi folks,

I have a i386 machine with a Fritz PCI ISDN card. The box dails into the net via i4b.
All seems to be fine, but sending large files (40kbyte) does not work.
I tried with ftp and SMTP (sendmail)

my sendmail log looks like that:

Mar 12 07:17:04 alice sendmail[10478]: h2C67XR10478: collect: premature EOM: Connection reset by dialin-145-254-064-252.arcor-ip.net

when I split the file into 10Kbyte parts, I can ftp them.

any idea?

I lowered the MTU but I did not help.

Thanks.
