Formmail CGI script stopped working on 1and1 shared hosting?
My formmail script recently stopped working under several domains hosted on the 1and1 shared servers. Not all domains, just some.
The reason seemed to be that the “$postmaster =” email address in formmail.pl was set to an address that was not with 1&1 (i.e. a domain not hosted with 1&1).
I know that UK2.net did a similar thing some while ago, but what they did was block anything which was not destined for a @uk2.net email address, which meant that if you wanted to use formmail.pl with UK2, you needed to sign up to a UK2.net mailbox as well. This was done to protect their servers from spam, but it was enough to make me stop using them.
