Hi,
I don't suspect that fetchmail was ever designed to handle that many
mail servers. Two things to try.
First, using 127.0.0.1 is the default for SMTP submission. Try
dropping "smtphost 127.0.0.1" from each line.
Secondly, if you're polling multiple accounts on a single server, try
specifying them together:
defaults
proto pop3
poll <ip>
username "a" password "a" smtpname "a" keep
username "b" password "b" smtpname "b" keep
poll <ip2>
username "c" password "c" smtpname "c" keep
This is all well and good, but it still doesn't say why it suddenly
spits out dns related ( looks like ) errors around the same point...
I'm sure i've used it for this size file before.
