dont think this is possible, but you may redirect mails to subfolder ( filter for big mails ) with i.e. sieve and exclude the subfolder from pop3 sight i blogged some example with virtual plugin, sorry german and not exactly what you asked for, its for auto sort spam mail , but perhaps it gives you an idea how solve your problem for the whole situation , why not simple allow only imap , and perhaps use folder acl etc , downloading only subjects first or some special folders etc to save bandwith should be possible with most mobile clients http://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve-spamfilter-regel-fur-pop3-nutzer/ Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Joerg Heidrich
