[Fetchmail-users] Migrating from 6.3.24 to 6.4.38

[Dennis P. <da...@be...>]

I have fetchmail (6.3.24) running on CentOS 7 and am moving it to Ubuntu 
fetchmail (6.4.38). I thought the move would be pretty much seamless but 
was wrong. Apparently there are differences in the fetchmailrc file that 
I am not understanding. I am using it for gmail. Here is a sanitized 
portion of my fetchmailrc:

*set logfile "/var/log/maillog"
set postmaster "mailman"
set bouncemail
set no spambounce
set properties ""
defaults:
         timeout 240
poll pop.gmail.com
         proto POP3
         user "uuu...@gm..."
         is uuuuuuuuu
         password 'kkkkkkkkkkkkkkkr'
         preconnect "echo `date '+%b %d %H:%M:%S'` uuuuuuuuu"
         ssl
         nokeep
         fetchall

*Here is the output when I run it:

*Old UID list from pop.gmail.com:

*At this point it seems to hang and does not proceed to the next
