I've been using Mailwasher for many years. Just over year ago my ISP migrated their mail system to an MS Exchange-based one,which required separate accounts for each of the e-mail addresses on my Demon sub-domain.
To be able to access multiple inboxes I used an old Mailwasher Pro for a month on trial. It was fairly quick. When I registered I got a newer version of Mailwasher Pro.
The current version is slow as hell. The licence has expired now and hey;re asking £16.95 for he year plus bank charges for overseas transactions.

It's hardly worth 20 quid for a piece of lethargic bloatware.

Are there any good alternatives? (free / lifetime licence)

Thanks in advance
