On Pop3 connector the minimum value for check accounts is 5 minute...Is it possible to reduce that value?Or better reduce it only for some accounts?
Please, don'tISPs don't like this kind of things5 mons is good enough for a service (e-mail) that relies on "best effort" principle
Having @Stefano_Zamboni advice in mind, the externalFreq property can be changed globally (not per user) from command line:
config setprop fetchmail externalFreq 7
The change won't be reflected in the UI, which could be missleading.
