Hello, since a couple of days I’ve been imposibilited to send mails larger than 800kb, the smaller mails work fine.
The connection seems to work fine, cause if I bypass the ISA server all mails are succesfully delivered.
I doble check cables and ethernet cards and all seems working just fine.
I’ve an Microsoft ISA Sever 2004 working on a Windows 2003 entreprise server. The computer has neither software or hardware modifications recently.
Both POP and HTTP servicies works perfeclty, only the SMTP have problems.
